Optical rotational self-assembly at air-water surface by a single vortex beam
Self-assembly and relevant quantitative measurements of 4 um polystyrene microspheres at air-water surface were realized by utilizing optical tweezers with a low-numerical-aperture (NA) and long-working-distance (WD) microscope objective. It showed that the rotation velocity of a single microsphere...
