Methods and apparatus for synthesizing labeled combinatorial chemistry libraries

Abstract

The present invention provides labeled synthetic libraries of random oligomers and methods and apparatus for generating labeled synthetic oligomer libraries. Each member of such a library is labeled with a unique identifier tag that specifies the structure or sequence of the oligomer. In a preferred embodiment of the present invention the identifier tag is a microchip that is pre-encoded or encodable with information that is related back to a detector when the identifier tag is pulsed with electromagnetic radiation.
