Fluorinated polyimide micro-objects (6–7.5 μm cross-sectional radius) fabricated using
reactive ion etching have been both optically trapped and simultaneously rotated in both
high and low relative–refractive index surrounding media. Symmetrical micro-objects with a
low relative–refractive index were optically trapped by exerting optical radiation pressure
through their center openings by using a strongly focused trapping laser beam. Micro-
objects were both trapped and rotated by the radiation pressure when the horizontal cross …
