The microtools were prepared with two-photon polymerization. Their shape enables the approach of the cells in any lateral direction. In the presented case, endothelial cells grown on vertical polymer walls were probed by the tools in a lateral direction. The use of specially shaped microtools prevents the target cells from photodamage that may arise during optical trapping. The position of the tools was recorded simply with video microscopy and analyzed with image processing methods. We critically compare the resulting Young's modulus values to those in the literature obtained by other methods. The application of optical tweezers extends the force range available for cell indentations measurements down to the fN regime. Our approach demonstrates a feasible alternative to the usual vertical indentation experiments.}, year = {2020}, eissn = {2072-666X}, orcid-numbers = {Fekete, Tamás/0000-0002-1557-845X; Molnár, Kinga/0000-0002-0596-2191; Vizsnyiczai, Gaszton/0000-0003-3245-3736; Ormos, Pál/0000-0003-2541-5686; Kelemen, Lóránd/0000-0001-7772-2165} } @article{MTMT:31355523, title = {Biological Microscopy with Undetected Photons}, url = {https://m2.mtmt.hu/api/publication/31355523}, author = {Búzás, András and Wolff, Elmar K. and Benedict, Mihály and Ormos, Pál and Dér, András}, doi = {10.1109/ACCESS.2020.3000740}, journal-iso = {IEEE ACCESS}, journal = {IEEE ACCESS}, volume = {8}, unique-id = {31355523}, issn = {2169-3536}, year = {2020}, eissn = {2169-3536}, pages = {107539-107548}, orcid-numbers = {Benedict, Mihály/0000-0003-3892-0235; Ormos, Pál/0000-0003-2541-5686} } @article{MTMT:31142384, title = {Multiview microscopy of single cells through microstructure-based indirect optical manipulation}, url = {https://m2.mtmt.hu/api/publication/31142384}, author = {Vizsnyiczai, Gaszton and Búzás, András and Aekbote Lakshman Rao, Badri and Fekete, Tamás and Grexa, István and Ormos, Pál and Kelemen, Lóránd}, doi = {10.1364/BOE.379233}, journal-iso = {BIOMED OPT EXPRESS}, journal = {BIOMEDICAL OPTICS EXPRESS}, volume = {11}, unique-id = {31142384}, issn = {2156-7085}, year = {2020}, pages = {945-962}, orcid-numbers = {Vizsnyiczai, Gaszton/0000-0003-3245-3736; Fekete, Tamás/0000-0002-1557-845X; Ormos, Pál/0000-0003-2541-5686; Kelemen, Lóránd/0000-0001-7772-2165} } @article{MTMT:30735098, title = {Direct writing of optical microresonators in a lab-on-a-chip for label-free biosensing}, url = {https://m2.mtmt.hu/api/publication/30735098}, author = {Kelemen, Lóránd and Lepera, E. and Horváth, Bence and Ormos, Pál and Osellame, R. and Vazquez, R.

Herein we report on a monolithic lab on a chip fabricated by a hybrid femtosecond laser micromachining approach, for label-free biosensing. It consists of a polymer WGM microresonator sensor integrated inside a glass microfluidic chip, presenting a refractive index change sensitivity of 61 nm per RIU. The biosensing capabilities of the device have been demonstrated by exploiting the biotin-streptavidin binding affinity, obtaining a measurable minimum surface density increase of 67 x 10(3) molecules per mu m(2).}, year = {2019}, eissn = {1473-0189}, pages = {1985-1990}, orcid-numbers = {Kelemen, Lóránd/0000-0001-7772-2165; Ormos, Pál/0000-0003-2541-5686} } @article{MTMT:30618258, title = {Optikai csipeszek.
