APPARATUS AND METHOD FOR FABRICATING, SORTING, AND INTEGRATING MATERIALS WITH HOLOGRAPHIC OPTICAL TRAPS

摘要

An apparatus and method for manipulating, effecting interaction of, photochemically transforming and/or sorting small dielectric particles or other materials are disclosed. The apparatus and method involves the use of one or more diffractive optical elements which each receive a laser beam and form a plurality of laser beams. These laser beams are operated on by a telescope lens system and then an objective lens element to create an array of optical traps for manipulating, effecting interaction of, photochemically transforming and/or small dielectric particles or other materials. One object of the invention is to provide an improved method and system for using optical traps to incorporate foreign matter into living cells. Another object of the invention is to provide an improved method and system to sort optically nonabsorbing particles from optically absorbing particles. Yet another object ot the invention is to provide an improved method and system to implement the fabrication of heterogeneous structures using spatially resolved photochemistry.
