N2 - The monodispersed birefringent anisotropic colloids of controllable shapes were analyzed. The idea of the process resides in starting with a liquid-crystal emulsion whose orientational order can be frozen by photopolymerizing the drops. Deformation of the drops before locking in the ordering allows different colloidal shapes to be explored. polarized optical microscopy and optical tweezing were employed to demonstrate both the optical and the geometric anisotropies of these particles. The method relies in obtaining a monodispers liquid-crystal emulsion that is photopolymerized to yield the desired colloids.
