WebIn this study, coated BTG microspheres with a PS coating have been computationally explored for the combination of optical trapping with microsphere-assisted microscopy. The PS coating thickness affects both the optical trapping efficiency and photonic nanojet (PNJ) property of the coated BTG sphere. WebMay 16, 2024 · The first experiment on optical trapping of silica microspheres with diameter 0.97 ... The surfaces of silica particles were coated with DMOAP silane to induce strong perpendicular anchoring of liquid crystal molecules and the silica microsphere dispersion was put inside a homeotropic nematic cell with a thickness much larger than the colloidal ...

WebUsing line optical tweezers, we quantify the dynamics of two DNA-coated microspheres as a function of DNA density and strength of the DNA-induced pair interaction potential. WebApr 11, 2024 · The fluorescent dye that provides an optical gain in our microlasers is added via swelling and subsequent trapping of the dye molecules in the PS microspheres. This process could change the refractive index of the microsphere and thus any absolute measurement of the external refractive index requires a calibration measurement where … WebAug 28, 2008 · Coated microspheres as enhanced probes for optical trapping, Proceedings of SPIE 10.1117/12.795389 DeepDyve DeepDyve Get 20M+ Full-Text Papers For Less Than $1.50/day.
