	abstract = {Microengines have shown promise for a variety of applications in nanotechnology, microfluidics, and nanomedicine, including targeted drug delivery, microscale pumping, and environmental remediation. However, achieving precise control over their dynamics remains a significant challenge. In this study, we introduce a microengine that exploits both optical and thermal effects to achieve a high degree of controllability. We find that in the presence of a strongly focused light beam, a gold-silica Janus particle becomes confined at the stationary point where the optical and thermal forces balance. By using circularly polarized light, we can transfer angular momentum to the particle, breaking the symmetry between the two forces and resulting in a tangential force that drives directed orbital motion. We can simultaneously control the velocity and direction of rotation of the particle changing the ellipticity of the incoming light beam while tuning the radius of the orbit with laser power. Our experimental results are validated using a geometrical optics phenomenological model that considers the optical force, the absorption of optical power, and the resulting heating of the particle. The demonstrated enhanced flexibility in the control of microengines opens up new possibilities for their utilization in a wide range of applications, including microscale transport, sensing, and actuation.},

The observed handedness of the rotation of the structure can be controlled by changing the relative positions of the constituent colloids. We show that the angular velocity of rotation is sensitive to the intensity of the incident optical fields and the size of the constituent colloidal entities. The emergence of rotational dynamics can be understood in the context of the asymmetric temperature distribution in the system and the relative location of the active colloid, which creates a local imbalance of optothermal torques in the confined system. Our work demonstrates how localized optothermal fields lead to directional rotational dynamics without explicitly utilizing the spin or orbital angular momentum of light. We envisage that our results will have implications in realizing Brownian engines and can directly relate to rotational dynamics in biological and ecological systems.},

The elliptic vortex beams cannot evolve as solitons due to their non-circular-symmetry, but can evolve as breathers in the nonlinear media without anisotropy. During breathing evolutions, the rotating phenomenon is observed. The rotations take place in both the vortex cores and the beam envelopes, which exhibit opposite rotating directions. The breathing and rotating evolutions both have close relations with the input power and the beam size. The analytical results are well confirmed by the numerical simulations.

This review provides an in-depth discussion on recent advances in chemical and mechanical sensors based on 3D nanostructures, which are rationally designed and manufactured by advanced 3D nanofabrication techniques that consider structural factors (e.g., porosity, periodicity, and connectivity).

State-of-the-art demonstrations of high-performance sensor devices such as supersensitive gas sensors and wearable strain sensors realized through designed 3D nanostructures are summarized.

Here, a robust enantioselective rotation of subwavelength chiral particles using lateral optical forces induced by a tightly focused azimuthally polarized beam is demonstrated. Although this focused field carries neither optical orbital angular momentum nor optical chirality, the lateral optical force can rotate the particle with opposite chirality around opposite directions, achieving an effective optical enantioseparation. Such a counterintuitive phenomenon is closely related to the transformation of the magnetic spin angular momentum of the focused field into the mechanical orbital angular momentum of the particle. In addition, the particle with different chirality parameters will be trapped in different orbits while with opposite chirality trapped in the same orbit, meanwhile its rotation direction is determined by the sign of the chirality parameter, which can realize an efficient chiral identification of single particles. The investigations may open up a new path toward light-induced rotation or probing of objects with different chirality parameters.},

This unusual tool has a wide application prospect because the non-contact and non-destructive advantages ideally suit the pressing need of bio-technology. However, most sorting methods and devices have been accomplished based on real-time one-by-one sorting, which ignored the sorting efficiency and is not applicable to high-capacity particles. Although more and more structured light beams are proposed to enhance the sorting efficiency, it is still not enough for desired applications. Here, we propose a method for the massive parallel sorting of particles: polygonal optical vortex (OV) beams are unwound by a geometric transformation to produce linear OV beams with kinked distributions. This structured light is used to greatly enhance the sorting efficiency. We adopt the fractal theory to illustrate the increase of the region over which the beam can interact with particles. We demonstrate that the gradient force of this beam is large enough to manipulate spherical particles in the Rayleigh regime of scattering. These results introduce new possibilities for high-capacity particle sorting.},

In this work, a Convolutional Neural Network (CNN) is trained to generate holograms, and its performance is compared to state-of-the-art iterative methods, both in terms of reconstruction quality and computation time. Here, a CNN built on the UNet architecture, capable of hologram generation, is presented. The network is trained on 4096 images of varying spatial frequencies, both generated by hand and from the DIV2K dataset. It is compared to the most common iterative method for hologram generation, namely the Gerchberg-Saxton (GS) algorithm and its modern and improved implementations. In reconstruction quality, the neural network outperforms the original implementation of GS when evaluating Mean Square Error (MSE), geometric error (GE), Structural Similarity Index Measurement (SSIM), and Peak Signal-Noise Ratio (PSNR) of 64 unseen test images. However, on the same test images, the network lacks behind the modern, optimized GS implementations in all error and accuracy measurements. The network does, however, achieve these results at a rate 70-280 times faster than the iterative methods, depending on the particular implementation of the GS algorithm, which corresponds to a possible generation rate of the network of 32 FPS on average.},

It is counterintuitive to observe the reversal of optical torque acting on an ordinary dielectric nanoparticle illuminated by an elliptically or circularly polarized light wave. Here, we demonstrate that negative optical torques, which are opposite to the direction of SAM, can ubiquitously emerge when elliptically polarized light waves are impinged on dielectric nanoparticles obliquely. Intriguingly, the rotation can be switched between clockwise and counterclockwise directions by controlling the incident angle of light.

Recently, it has attracted much attention for its potential in the classical and quantum regimes. In this work, we review the progress of experiments and applications of optically induced rotation. First, we introduce the basic exploration of angular momentum. Then, we cover the development and application of optical rotation induced by orbital angular momentum, and the spin angular momentum is presented. Finally, we elaborate on recent applications of the optical rotation technique in high vacuum. As precise optical manipulation in a liquid medium enters its maturity, optical tweezers in high vacuum open a new path for the high-speed micro-rotor.},

	abstract = {The fastest-spinning man-made object is a tiny dumbbell rotating at 5 GHz. The smallest wind-up motor is constructed from a DNA molecule. Picoliter volumes of fluids are remotely controlled and their viscosity precisely measured using microrheometers based on miniscule rotating particles. Theoretical predictions for extraordinarily weak forces related to the presence of dark matter, dark energy and vacuum-induced friction might be revealed, and the surprising properties of light have already been experimentally evidenced. All of these exciting landmarks have only been possible thanks to the torque exerted by light, which enables rotation of an optically trapped particle. Here, we review how light can impart torque on optically trapped particles, paying close attention to the design of the properties of both the particle and the light field. We detail how the maximum achievable rotation speed is limited by the environment, but can simultaneously be used to infer properties of the surrounding medium and of the light field itself. We also review the state-of-the-art applications of light-driven rotors, as well as proposals for the next generation of measurements, particularly at the classical-quantum interface, which can be performed using rotating optically trapped objects. © 2020 The Author(s).

Despite significant advances in the field and successful demonstration of a wide range of applications, microrobots have yet to become the preferred choice outside a laboratory environment. After introducing available microrobotic propulsion and control mechanisms, microrobots that are manufactured and powered by light are focused herein. Referring to pioneering works and recent interesting examples, light is presented not only as a fabrication tool, by means of two-photon polymerization direct laser writing, but also as an actuator for microrobots in both hard and soft stimuli-responsive polymers. In this scenario, a number of challenges that yet prevent polymeric light-powered microrobots from reaching their full potential are identified, whereas potential solutions to overcome said challenges are suggested. As an outlook, a number of real-world applications that light-powered microrobots should be particularly suited for are mentioned, together with the advances needed for them to achieve such purposes. An interdisciplinary approach combining materials science, microfabrication, photonics, and data science should be conducive to the next generation of microrobots and will ultimately foster the translation of microrobotic applications into the real world.},

Even though the developments of smart materials and advanced micro/nanomanufacturing are flouring, how to achieve intelligent shape-morphing machines at micro/nanoscales is still significantly challenging due to the lack of design methods and strategies especially for small-scale shape transformations. This review is aimed at summarizing the principles and methods for the construction of intelligent shape-morphing micromachines by introducing the dimensions, modes, realization methods, and applications of shape-morphing micromachines. Meanwhile, this review highlights the advantages and challenges in shape transformations by comparing micromachines with the macroscale counterparts and presents the future outlines for the next generation of intelligent shape-morphing micromachines.},

Here, we demonstrate the controlled orbital rotation of a single fluorescent nanodiamond trapped by a gold trimer nanoantenna irradiated by a rotating linearly polarized light or circularly polarized light. Remarkably, the rotation direction is opposite to the light's polarization rotation. We numerically show that this inversion comes from sequential excitation of individual nanotriangles in the reverse order when the linear polarization is rotated, whereas using a circular polarization, light-nanoparticle angular momentum transfer occurs via the generation of a Poynting vector vortex of reversed handedness.

After a brief general introduction on optical tweezers, we focus on describing and comparing the various available calibration techniques. Then, we discuss some cutting-edge applications of optical tweezers in a liquid medium, namely, to study single-molecule and single-cell mechanics, microrheology, colloidal interactions, statistical physics, and transport phenomena. Finally, we consider optical tweezers in vacuum, where the absence of a viscous medium offers vastly different dynamics and presents new challenges. We conclude with some perspectives for the field and the future applications of optical tweezers.

	abstract = {Computer Generated Holography (CGH) promises unprecedented capabilities for a variety of applications in Optics and Photonics. However, one of the biggest challenges for CGHs is the fundamental tradeoff between algorithm runtime and achieved reconstruction fidelity and efficiency while maintaining light projections at real-time frame rates. In addition, the light projection quality achieved by most CGH-modalities are rather low due to the mismatch between the optical wave propagation of the applied Spatial Light Modulator (SLM) and its simulated model. A promising new avenue of CGH, neural holography, utilizes machine learning models in the generation of single and multi plane holograms. Neural network generated holograms have the distinct advantage that inference is performed in constant time without the need for iterative calculations of the phase SLM pattern. This allows the networks to generate holograms 3-500 times faster than traditional iterative algorithms, which enables the applications dependent on real-time holography. State-of-the-art implementations of neural holography [1, 2] furthermore achieve higher accuracy than traditional iterative algorithm, when compared to target images. Applications of these SLM-encoded CGHs include all areas where a fast and parallel one-or two-photon light excitation is needed such as in Laser Material Processing, Additive Manufacturing and 3D printing, Neurophotonics and Optogenetics, Laser Image Projection and many more. © 2021 SPIE.},

Meanwhile, the significant photomechanical behaviors were observed for the crystals with different shapes. The crystals of 4-FBAc (block-like), 4-ClBAc (block-like) and 4-BrBAc (rod-like) showed lightinduced cracking, salient and cracking behaviors, respectively. Interestingly, the crystals of 4-FBAc (needle-like) and 4-IBAc (needle-like) bent away from the UV light (E-*Z isomerization) firstly, then bent toward the source with the increasing of the irradiation or heating time (structure relaxation and Z-*E isomerization). The theoretical study also showed that the molecules could undergo reversible E-Z isomerization reactions under UV irradiation and heating condition. Interestingly, the passive optical (635 nm) output direction of the crystal of 4FBAc could be controlled by UV light. When mechanical force was applied or removed, the needle-like crystals of 4-FBAc and 4-IBAc exhibited reversible elastic bending properties. Analysis of the single crystal data suggested that C-HMIDLINE HORIZONTAL ELLIPSIS pi and H-bonds were responsible for the flexibility. So, the elastic organic molecular crystals based on acylhydrazone derivatives could be used as the candidate for crystal actuators and position-controllable optical transducer.},

	abstract = {Microfluidics is the technology of fluid manipulation in channels with dimensions of tens of micrometers; it has emerged in recent years as a distinct new area of research thanks to its application in many diverse fields, such as chemistry, biology, medicine, and physical sciences. A strong motivation in microfluidic research comes from the development of lab-on-chip (LOC) devices, which are expected to bring a revolution in the field of chemistry and biology as integrated circuits did in computation capabilities. LOCs are microsystems capable of integrating entire biological or chemical laboratories in a single chip, thanks to the integration of microfluidic channels and active or passive components, such as filters, valves, mixers, and many others. The high level of integration required in LOCs creates a demand for advanced fabrication technologies that are capable of miniaturizing several key fluidic components with the aim of improving the compactness of these devices and their functionalities. In this framework, two-photon polymerization (2PP) represents a very interesting technology since it has unique three-dimensional capabilities, extreme resolution, and sufficient versatility to be combined with other microfabrication technologies.

Microfluidic techniques with various functions and extensions have often been used for such purposes to investigate the mechanical properties of microscopic objects such as biological cells. One of such extensions proposed in this context is a real-time visual feedback manipulation system, which is composed of a high-speed camera and a piezoelectric actuator with a single-line microfluidic channel. Although the on-chip manipulation system enables us to control the 1 degree-of-freedom position of a target object by the real-time pressure control, it has suffered from unintended changes in the object orientation, which is out of control in the previous system. In this study, we propose and demonstrate a novel shear-flow-based mechanism for the control of the orientation of a target object in addition to the position control in a microchannel to overcome the problem of the unintended rotation. We designed a tributary channel using a three-dimensional hydrodynamic simulation with boundary conditions appropriate for the particle manipulation to apply shear stress to the target particle placed at the junction and succeeded in rotating the particle at an angular velocity of 0.2 rad/s even under the position control in the experiment. The proposed mechanism would be applied to feedback controls of a target object in a microchannel to be in a desired orientation and at a desired position, which could be a universally useful function for various microfluidic platforms. © 2020 Author(s).},

In the process of machining, the shape and intensity distribution of focus spot are changed by some processing parameters, which affect the processing accuracy and surface quality. Based on Fresnel diffraction theory and the intensity distribution function of focal spot, the focal spot shape is simulated and the main factors affecting the light intensity distribution are analyzed theoretically and simulated numerically. We propose a shaping method to improve the asymmetric shape of the facula by adding a prefocusing lens. According to the mechanism of femtosecond-laser super-resolution processing, we propose a beam shaping method using four-ring complex transmittance phase plate to achieve super-resolution processing. The phase plate was optimized on the global optimization algorithm and genetic algorithm. The validation experiment was carried out by scanning the photochromic material film with pulsed laser and reading the fluorescence signal of the photochromic point with single photon confocal. The experimental results show that the facula distribution is approximately symmetrical, and the size of facula is decreased obviously. The compression ratio is basically consistent with the theoretical calculation results. Therefore, super-resolution processing can be achieved by adding pre-focusing lens and phase plate to shaping the laser beam. The results of theoretical and experimental studies provide sufficient basis for improving the machining accuracy and surface quality of microdevices.},

Yet despite the many unique characteristics and promising advantages of EV beams, such as transverse momentum and quantized orbital angular momentum, there remains a limited understanding of their fundamental interactions with matter at the atomic scale. Collisions between EV projectiles and atomic targets can provide some insight into these interactions and we present here fully differential cross sections (FDCS) for ionization of excited state atomic hydrogen targets using EV projectiles. We show that the projectile's transverse momentum causes the ionized electron angular distributions to be altered compared to non-vortex projectiles and that the ionized electron's ejection angle can be controlled by adjustment of the vortex opening angle, a feature unique to vortex projectiles. Additionally, an inherent uncertainty in the projectile's momentum transfer leads to a broadening of the classical binary peak, making signatures of the target electron density more readily observable. FDCS for aligned 2p targets exhibit structures can be used to determine the alignment.},

The intrinsic OAM of light beams arises due to the helical wavefronts of phase singularities. In phase singularities, circulating phase gradients and, in polarization singularities, circulating phi(12) Stokes phase gradients are present. At the phase and polarization singularities, undefined quantities are the phase and phi(12) Stokes phase, respectively. Conversion of circulating phase gradient into circulating Stokes phase gradient reveals the connection between phase (scalar) and polarization (vector) singularities. We demonstrate this by theoretically and experimentally generating polarization singularities using phase singularities. Furthermore, the relation between scalar fields and Stokes fields and the singularities in each of them is discussed. This paper is written as a tutorial-cum-review-type article keeping in mind the beginners and researchers in other areas, yet many of the concepts are given novel explanations by adopting different approaches from the available literature on this subject.},

Generally, the thickness of spherical microparticles is assumed to be the diameter which renders the particle appear cylindrical. We test this hypothesis for sizes relevant towards optical tweezers manipulation. We find that for a range of particles from the Rayleigh regime to the early Mie regime, the approximation holds good.},

Three-dimensional (3D) laser structuring of materials employing ultrashort pulses is widely used in photopolymer rapid prototyping spanning microoptical elements, optical actuators, microfluidic chips, scaffolds for cell growth and tissue engineering, templates for plasmonic metamaterials, and photonic crystals (PhC). It is one of the most precise additive manufacturing technologies ever developed in both scientific and industrial fields. Despite already appearing as commercially available setup still some active engineering is being carried out, for instance, implementation of active autofocusing and machine vision for sample detection and positioning. In order to achieve resolution of structuring required for microoptical and PhC structures operational at visible spectral range, the feature dimensions should be controlled with 10 nm spatial precision. Despite recent advances in techniques’ versatility, regarding specifically optical applications, the research inherits some gaps due to an initial pure engineering approach to 3D fabrication. For instance, the materials designed for 3D direct laser writing (DLW) are not fully (or barely at all) characterized and their optical performance and reliability have to be established. Thus, despite the DLW technique being mature and commercially available, some standard knowledge for its application in fabricating microoptical and photonic devices must be considerably improved, namely, the linear and nonlinear properties of the material itself, its modulation due to DLW structuring and postprocessing, taking into account various side effects and artifacts, e.g., an optical resistance.

Converting green, recyclable light energy into the mechanical energy of a micromotor is undoubtedly an exciting challenge. However, the performance of current light-induced micromotor devices is unsatisfactory, as the light-to-work conversion efficiency is only 10(-15)-10(-12). In this paper, we propose and demonstrate a laser-induced rotary micromotor operated by Delta alpha-type photopheresis in pure liquid glycerol, whose energy conversion ratio reaches as high as 10(-9), which is 3-6 orders of magnitude higher than that of previous light-induced micromotor devices. In addition, we operate the micromotor neither with a light field carrying angular momentum nor with a rotor with a special rotating symmetrical shape. We just employ an annular-core fiber to configure a conical-shaped light field and select a piece of graphite sheet (with an irregular shape) as the micro-rotor. The Delta alpha-type photophoretic force introduced by the conical-shaped light field drives the rotation of the graphite sheet. We achieve a rotation rate up to 818.2 r/min, which can be controlled by tuning the incident laser power. This optical rotary micromotor is available for twisting macromolecules or generating vortex and shear force in a medium at the nanoscale. (C) 2020 Chinese Laser Press},

The optical beam exhibits larger off-axis velocity when the vortex dipole is parallel to the major axis of the host elliptic beam.

In this work, gel photoresists were prepared by embedding photothermal surface-modified Fe3O4 nanoparticles (NPs) into a mixture that included a photoinitiator, photosensitizer, monomers, crosslinkers and solvents. Macroscopic poly(N-isopropylacrylamide) (PNIPAM)/nanoFe(3)O(4) hydrogels were prepared by ultraviolet photopolymerization of gel photoresists, which showed good temperature-responsive volume changes and light-triggered bending deformation. Then the two-photon polymerization (TPP) microfabrication properties of gel photoresists with 0, 0.48 and 0.95 wt% Fe3O4 NPs were investigated in detail. Importantly, after the TPP microfabrication and subsequent solvent-exchange procedure, a double-armed near-infrared (NIR)-light-driven three-dimensional (3D) hydrogel microcantilever with a size of similar to 26 mu m was successfully fabricated. The hydrogel microactuator had a fast response time of similar to 0.033 s in water under NIR radiation and showed good reversibility. Furthermore, the distance between the two arms of the hydrogel microcantilever could be manipulated by controlling the laser focus and incident laser power.},

	abstract = {Multi-Photon Polymerization (MPP) is a technique used to fabricate complex micro-scale 3D structures using ultra-short laser pulses. Typically, MPP is used to manufacture micron-scale components in photopolymer materials. However, the development of micron scale processes that can produce components from multiple materials within a single manufacturing step would be advantageous. This would allow the inclusion of particles that are manipulated and embedded within structures with sub-micron feature sizes. To achieve this, an MPP system was combined with an optical trapping (OT) setup in order to independently manipulate microparticles in the x, y and z planes. Particles were transported into the fabrication site using the OT and encapsulated using the MPP laser. Here it is shown that combining the OT capabilities with an additive manufacturing technique enables the production of complex multi-material artifacts.},

	abstract = {The physics of optical vortices, also known as twisted light, is now a well-established and a growing branch of optical physics with a number of important applications and significant interdisciplinary connections. Optical vortex fields of widely varying forms and degrees of complexity can be realised in the laboratory by a host of different means. The interference between such beams with designated orbital angular momenta and optical spins (the latter is associated with wave polarisations) can be structured to conform to various geometrical arrangements. The focus of this review is on how such tailored forms of light can exert a controllable influence on atoms with which they interact. The main physical effects involve atoms in motion due to application of optical forces. The now mature area of atom optics has had notable successes both of fundamental nature and in applications such as atom lasers, atom guides and Bose-Einstein condensates. The concepts in atom optics encompass not only atomic beams interacting with light, but atomic motion in general as influenced by optical and other fields. Our primary concern in this review is on atoms in structured light where, in particular, the twisted nature of the light is made highly complex with additional features due to wave polarisation. These features bring to the fore a variety of physical phenomena not realisable in the context of atomic motion in more conventional forms of laser light. Atoms near resonance with such structured light fields become subject to electromagnetic fields with complex polarisation and phase distributions, as well as intricately structured intensity gradients and radiative forces. From the combined effect of optical spin and orbital angular momenta, atoms may also experience forces and torques involving an interplay between the internal and centre of mass degrees of freedom. Such interactions lead to new forms of processes including scattering, trapping and rotation and, as a result, they exhibit characteristic new features at the micro-scale and below. A number of distinctive properties involving angular momentum exchange between the light and the atoms are highlighted, and prospective applications are discussed. Comparison is made between the theoretical predictions in this area and the corresponding experiments that have been reported to date.},

	abstract = {Materials with microscale structures are gaining increasing interest due to their range of technical and medical applications. Additive manufacturing approaches to such objects via laser two-photon polymerization, also known as multiphoton fabrication, enable the creation of new materials with diverse and tunable properties. Here, we investigate the properties of 3D structures composed of organometallic polymers incorporating aluminium, titanium, vanadium and zirconium. The organometallic polymer-based materials were analysed using a variety of techniques including SEM, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy analysis and contact angle measurements and their biocompatibility was tested in vitro. Cell viability and mode of death were determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay and acridine orange/ethidium bromide staining. Polymers incorporating Al, Ti and Zr supported cell adhesion and proliferation, and showed low toxicity in vitro, whereas the organometallic polymer incorporating V was shown to be cytotoxic. Inductively coupled plasma optical emission spectrometry suggested that leaching of the V from the organometallic polymer is the likely cause of this. The preparation of the organometallic polymers is straightforward and both simple 2D and complex 3D structures can be fabricated with ease. Resolution tests of the newly developed organometallic polymer incorporating Al show that suspended lines with widths down to 200 nm can be fabricated. We believe that the materials described in this work show promising properties for the development of objects with sub-micron features for biomedical applications (e.g. biosensors, drug delivery devices, tissue scaffolds etc.).

The flexibility of optical trapping methods facilitates real-time monitoring of the dynamics of biological processes in model systems and even in living cells. Different optical trapping and manipulation approaches allow displacement of nanostructures with subnanometer precision and force measurements with femtonewton precision. Due to inherent constraints of optical methods, most optical trapping experiments are performed in water or simple aqueous solutions. However, in recent years, there is an ever-growing interest of shifting from simple aqueous media towards more biologically-relevant media. Precise optical trapping and manipulation, combined with state-of-the-art microfabrication, will enable the development of microrobotic "surgeons" with tremendous potential for biomedical and microengineering applications.

As all the measurements are conducted without physically contacting the system under study, they also avoid complications related to contamination and tissue damage. From the manipulation of fluorescent nanodiamonds to chromosomes, cells, and free-swimming bacteria, OTs have now been extended to challenging biological systems such as the vestibular system in zebrafish.

Underutilized precision in the typical fabrication process allows this subtractive technique to dramatically reduce the minimum achievable feature size. Moreover, since the postprocessing occurs in a dry environment, high aspect ratio features that cannot survive the typical fabrication route can also be achieved. Finally, it is shown that the technique also provides a pathway to realize structures that otherwise are too delicate to be fabricated with TPP, as it enables to introduce temporary support material that can be removed with the plasma. As such, the proposed approach grants access to a massively expanded design domain, providing new capabilities that are long sought in many fields, including optics, biology, robotics, and solid mechanics.},

Recent advancements have shown that Airy beams can also be produced using matter waves with many of the same unique characteristics of their optical counterparts. We present here a study of the recovery time of damaged matter Airy wave packets in free space and a nonlinear Kerr-type medium. We show that in free space the recovery time increases approximately linearly with mass and is independent of other kinematical parameters such as momentum, velocity, and spatial width. In the Kerr-type medium, recovery time is decreased compared to free space and does not scale linearly with mass. In order to study matter Airy beams, we introduce the Path Integral Quantum Trajectory model as a new computational tool for the study of non-relativistic, quantum mechanical wave packets and demonstrate its effectiveness in dealing with heavy particle dynamics.},

The simplest case is where both beams are doughnut beams which have the same linear polarisation. The total fields of this system are shown to display novel amplitude and phase distributions and are shown to give rise to a ring or a finite ring lattice composed of double rings and single central ring. When the beams have slightly different frequencies the ring lattice pattern becomes a finite set of rotating Ferris wheels and the whole pattern also moves axially between the focal planes. We show that the fields of such an axially shifted pair of counter-propagating LG beams generate trapping potentials due to the dipole force which can trap two-level atoms in the components of the ring lattice. We also highlight a unique feature of this system which involves the creation of a new longitudinal optical atom trapping potential due to the scattering force which arises solely when d not equal 0. The results are illustrated using realistic parameters which also confirm the importance of the Gouy and curvature effects in determining the ring separation both radially and axially and gives rise to the possibility of atom tunnelling between components of the double rings.},

The resultant patterns exhibit revolving and spinning rotations similar to the Sun-Earth system. The revolving-typed rotation comes of the overall OAM, while the spinning-typed rotation results from the respective OAM of the constituent beam. A kind of soliton patterns can stably exist, for which a vortex is nested centrally in the rotating square-shaped optical envelope and four peaks appear at four corners. The centrally nested vortex splits into two single vortex for r not equal 1, with r being the power ratio between the two constituent beams. The two single vortexes align vertically for r < 1 and horizontally for r > 1, and their spacing increases with vertical bar r - 1 vertical bar.

Importantly, DM enables the inexpensive realization of 3D designs that are impossible or very difficult to mold.

Interestingly, their molecular crystals exhibit significant photomechanic effects and the H-1 NMR spectral changes for the microcrystals before and after UV irradiation suggest that photodimerization is the driving force for the light-induced macroscopic mechanic movements. The needle-like crystals of BOV1N bend away from the UV light upon irradiation for several seconds. Such rapid elastic deformation could be repeated several times. It should be noted that -type and -type cyclobutane derivatives D-BOV1N (the dimer of BOV1N) are afforded as the main product and byproduct, respectively, after the microcrystals were exposed to 365 nm light for 5 min. Since the photo-induced [2+2] cycloaddition shortens the distance of the olefin pairs and makes the terminal units stretch outside the molecular long axle, the strain in the phototropic surface of the crystal can be yielded and accumulated. The release of the accumulated strain leads to the bending of the needle-like crystals backwards to the UV light. Thus, it was reasonable that the thinner fibers exhibited more rapid and significant movements on account of the high topo-photochemical reaction efficiency. The molecular crystals of BOV1NF, BOV2N, and BOV2NM exhibited similar photomechanic effects. We also found that the UV irradiation parallel to the long axis of crystals would not drive the crystals to move. On the contrary, the light-induced slipping and swinging of the needle-like crystal of BOV1NM is observed due to the low dimerization efficiency. Thus, the molecular crystals based on the naphthylvinylbenzoxazole derivatives become new platforms for the efficient light-mechanical energy conversion.},

Here, we propose a theoretical prototype of a micro-turbine that is powered purely by an external diffusive heat or mass flux. The turbine rotates perpendicular to the external thermal or chemical gradient due to fore-and-aft asymmetric thermophoresis or diffusiophoresis. Thus, its performance does not need alignment. The prototype turbine is validated by means of computer simulations. The results show that the angular velocity of the turbine sensitively depends on its structure and interactions with the solvent. This perpendicular-axis phoretic turbine provides large flexibility and the possibility to exploit existing thermal or chemical energies at small scales.},

Here we report a sustained self-starting orbital motion of a clamped elongated nanostructure, a glass-fiber nanospike, when a CW laser beam is focused axially onto its tip. Analysis shows that photophoretic antitrapping forces, acting on the nanospike with a delayed response, introduce optomechanical gain into the mechanical motion, overcoming the intrinsic mechanical dissipation and resulting in growth from noise of oscillations at the resonant frequency of the nanospike. These photophoretic forces further enable phase-locking of the orthogonal fast and slow vibrations of the nanospike (induced by slight mechanical anisotropy), giving rise to a self-sustained orbital motion. The locked phase of orbital motion can be changed by tuning the gas pressure and adjusting the geometrical asymmetry of the system. This light-driven nanoengine opens up a new degree of freedom for controlling the rotational motion of elongated nano-objects.},

Nevertheless, the fabrication yield and quality of the transferred nanostructures are often limited by the merging of the surface patterns of replica stamps during transfer printing. Here, an nTP technology was developed to fabricate large-area and crack-free 3D multilayer nanostructures. Instead of directly depositing materials on the patterned flexible stamp in conventional nTPs, we transferred the nanostructures straightforwardly onto an attached polydimethylsiloxane slab by removing a sacrificial water-soluble poly(acrylic acid) film, which can avoid the cracking of metal film and the failures of printing nanostructures 500 rim onto target substrates. Based on this approach, subwavelength-thick polarization rotators working at infrared wavelengths were fabricated. Excellent performance of linear polarization rotation over a broadband was realized. This nTP approach could complement existing fabrication techniques and benefit the development of various functional nanostructures with complex multilayer hierarchies.},

The latest approach to address all these issues is to employ natural swimmers with computer control to deliver cargo instead resulting in micro cybernetic systems.
