Paper Abstract

The array biosensor has been developed for simultaneous analysis of multiple samples for multiple analytes. A patterned array of capture antibodies is immobilized on the surface of a planar waveguide and a sandwich immunoassay conducted using a cocktail of fluorescent tracer antibodies. Upon excitation of the fluorescent label using a 635 nm diode laser, a CCD camera detects the pattern of fluorescent antigen:antibody complexes on the sensor surface. Image analysis software correlates the position of fluorescent signals with the identity of the analyte. The assays are fast, sensitive, and specific.
