	abstract = {Multiwalled carbon nanotubes (MWCNTs) and nanocomposite made from MWCNTs and Pt nanoparticles (Pt-MWCNTs) were used as bulk modifiers of screen-printed carbon electrodes (SPCEs). Cyclic voltammetric and amperometric measurements were performed by the homemade substrate electrodes, the bare SPCE and the modified ones (MWCNT-SPCE and Pt-MWCNT-SPCE), with aim to investigate their applicability for determination of H2O2 in phosphate buffer solution (0.1 M; pH 7.50) as supporting electrolyte. Pt-MWCNT-SPCE showed improved analytical performances including the significant decrease in overpotential of H2O2 compared to SPCE and MWCNT-SPCE. So, Pt-MWCNT-SPCE served as substrate electrode for design of a simple first-generation biosensor made from glucose oxidase (GOx) and Nafion® forming the GOx/Pt-MWCNT-SPCE for reliable determination of glucose via its enzymatic by-product, the H2O2. The surface morphology characterization by scanning electron microscopy confirmed the presence of immobilized spherical shaped biosensing units at the GOx/Pt-MWCNT-SPCE. In the case of amperometry of glucose, optimal potential for the working electrode was − 0.50 V vs. SCE, and a satisfactory linearity was obtained in the tested concentration range from 65.8 to 260.6 μg mL−1, with estimated LOQ of 35.0 μg mL−1. The developed cost-effective amperometric method in combination with GOx/Pt-MWCNT-SPCE was successfully applied for the determination of glucose in selected food samples: white grapes and glucose tablets. The obtained results were in good agreement with those received by the alternatively used commercially available glucometer and by the producer declared value in the case of the tablet sample as well. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.},

		transmitting 125 micrometer optical fiber and a 9 micrometer carbon monofilament to 
		form an electrical lead element, which is contained in a borosilicate glass sheathing 
		coaxial arrangement ending with a micrometer-sized carbon tip. This novel unit 
		design is stiff and slender enough to be used for targeting deep brain areas, and may 
		cause less tissue damage compared with previous models. The center-positioned 
		carbon fiber is less prone to light-induced artifacts than side-lit metal 
		microelectrodes previously presented. The carbon tip is capable of not only 
		recording electrical signals of neuronal origin but can also provide valuable surface 
		area for electron transfer, which is essential in electrochemical (voltammetry, 
		amperometry) or microbiosensor applications. We present details of design and 
		manufacture as well as operational examples of the newly developed single micro-
		optrode, which includes assessments of 1) carbon tip length–impedance relationship, 
		2) light transmission capabilities, 3) photoelectric artifacts in carbon fibers, 4) 
		responses to dopamine using fast-scan cyclic voltammetry in vivo, and 5) 
		optogenetic stimulation and spike or local field potential recording from the rat brain 
		transfected with channelrhodopsin-2. With this work, we demonstrate that our novel

		stimulation when needing to be combined with extracellular recording,

They were characterized by cyclic voltammetry and hydrodynamic chronoamperometry in solution of pH 7.5. Both electrodes were then modified with glucose oxidase (GOx) by drop-coating a solution of GOx and Nafion® on their surface. Glucose can be determined via enzymatically formed H2O2. In an alternative approach, gold nanoparticles (5 nm) were incorporated into the biolayer of the electrodes. The resulting electrodes of type GOx/Pd-MWCNT-SPCE and GOx-Au/Pd-MWCNT-SPCE showed acceptable analytical performance at working potentials between −0.20 V and −0.50 V in case of hydrodynamic chronoamperometry. Both electrodes can be operated best at a working potential of −0.40 V vs SCE, with acceptable linearity of the methods in sub mM concentration ranges and with LOQs of 0.14 mM and 0.07 mM for glucose for the GOx/Pd-MWCNT-SPCE and GOx-Au/Pd-MWCNT-SPCE, respectively. Incorporation of gold nanoparticles prolongs the operational lifetime of the electrodes by two weeks. The GOx/Pd-MWCNT-SPCE based method was applied to the determination of glucose in multifloral honey, and the GOx-Au/Pd-MWCNT-SPCE method to the determination of glucose in blood serum. In both cases there was a good agreement with the results obtained by commercially available equipment for determination of glucose.},

	abstract = {Abstract In this comparative study a traditional paraffin oil and graphite powder based carbon paste electrode (CPE) was surface modified with multiwalled carbon nanotubes (MWCNTs) and with composites of MnO2-MWCNT or Pt-MWCNT by drop coating method to prepare simply, sensitive and reliable voltammetric sensors either for the determination of H2O2 or after additional modification of the appropriate sensor surfaces with glucose oxidase (GOx) for the determination of glucose via H2O2 in selected samples. The scanning electron microscopic characterization in combination with energy dispersive X-ray spectrometry of the composite materials confirmed that the mediators, MnO2 and Pt, are randomly distributed on the surface of the MWCNTs, and in both cases represent nearly 5% (m: m) of the modifiers expressed as Pt and Mn. Cyclic voltammetric (CV) investigations were performed in acetate (pH 4.50), phosphate (pH 7.50) and borate (pH 9.18) buffers to characterize the basic electrochemical behaviors and to select the working potentials suitable for hydrodynamic chronoamperometric (HA) determination of H2O2 under different circumstances. The CV responses showed that in slightly alkaline media all investigated electrodes, i.e., CPEs unmodified and modified with plain MWCNTs and MWCNTs based composites are in principle applicable, but with different efficiency at different potentials, with favorable reduction and acceptable oxidation of H2O2 at the Pt-MWCNT/CPE and predominately oxidation at the MnO2-MWCNT/CPE. The reproducibility of the responses with the MnO2-MWCNT/CPE is poor, but can be improved by electrochemical conditioning. The latter one performed well in alkaline supporting electrolyte (pH 9.18), while in the case of the Pt-MWCNT/CPE the signals are much better established in slightly acidic medium (pH 4.50). The analytical methods were optimized, mainly with the Pt-MWCNT/CPE as the preferential electrode, in terms of pH and working potential for the HA determination of H2O2 in spiked milk samples including the development of an appropriate sample treatment procedure. This electrode was also used for the design of a very simple and reliable first generation oxidase biosensor for determination of glucose content in human infusion via its enzymatic reaction product H2O2.},
