LASER TRAPPING AND METHOD FOR APPLICATIONS THEREOF

摘要

This invention provides laser trapping designed to trap a microparticle or a group of microparticles by scanning at least a focused laser beam at high speed. This laser trapping make it possible to control the formation of microparticles into a specified pattern according to the scanning form of the focused laser beam, fix and transport said pattern, and trap and manipulate the microparticles with lower index of refraction than that of a medium, or other photoreflective microparticles such as a metal. Consequently, with increasing degree of freedom of processing and modification on various microparticles, the field of application expands.
