Abstract
Methods and devices are provided for the trapping, including optical trapping; analysis; and selective manipulation of particles on an optical array. A multi-channel device parcels a light source into many points of light transmitted through an optical array of fibers or conduits, preferably where the individual points of light are individually controllable through a light controlling device. Optical properties of the particles may be determined by interrogation with light focused through the optical array. The particles may be manipulated by immobilizing or releasing specific particles, separating types of particles, etc.
Claims31
A device for parallel trapping of multiple dielectric particles, comprising:
- an optical array comprising a plurality of strands disposed coaxially along their lengths to form a single, discrete construction, wherein said array parcels a beam of light into individual beams of light, wherein the distal terminus of each strand is light focusing and wherein each strand is connectable to a detector.
