Based on arguments from geometrical o ptics, we hypothesized that using ant i-re ection-coated microspheres would reduce scattering and lead to stronger trapping. We designed, fabricated, and characterized polystyrene (PS) microspheres coated with silica (SiO x) to test whether the trap stiness of optical tweezers can be improved.
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.
