Abstract
A process for optically sorting a plurality of particles includes: providing a particle receiver; producing particles; receiving the particles by the particle receiver; receiving a light by the particle receiver; producing a standing wave optical interference pattern in an optical interference site of the particle receiver from the light; subjecting the particles to an optical gradient force from the standing wave optical interference pattern; deflecting the particles into a plurality of deflected paths to form the sorted particles from the particles; and propagating the sorted particles from the optical interference site through the deflected paths to optically sort the particles.
