An apparatus and system are provided for simultaneously analyzing a plurality of analytes anchored to microparticles. Microparticles each having a uniform population of a single kind of analyte attached are disposed as a substantially immobilized planar array inside of a flow chamber where steps of an analytical process are carried out by delivering a sequence of processing reagents to the microparticles by a fluidic system under microprocessor control. In response to such process steps an optical signal is generated at , the surface of each microparticle which is characteristic of the interaction between the analyte carried by the microparticle and the delivered processing reagent. …

Why it's free to use
- Filed May 22, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 22, 2018.
