Abstract:
Improved synthesis beads for use in combinatorial synthesis processes that includes at least one bead sorting step, wherein said beads include;(a.) a region on which is disposed a growth matrix,(b.) a molecular anchoring site attached to said growth matrix and(c.) a photoemissive region;wherein the improvement comprises a plurality of vertical cavity surface emitting lasers in said photoemissive region for radiating electromagnetic radiation over each of a plurality of different predetermined wavelength bands, said wavelength bands being sufficiently narrow to allow said wavelength bands to be distinguished from one another when said lasers are emitting radiation simultaneously, whereby the application of electromagnetic radiation to said beads sufficient to stimulate simultaneous lasing activity in said surface emitting lasers, when used in connection with at least one bead sorting step, causes said surface emitting lasers to emit a predetermined combination of wavelength bands that allows a bead to be distinguished from a plurality of other beads that emit electromagnetic radiation at different combinations of wavelength bands.
