Abstract:
An apparatus for detecting at least one receptor in at least one biological sample in a flow stream for at least one of immunoassays, complex genetic analyses, and enzymatic assays, the biological sample including at least one indicator indicating a presence of the at least one receptor upon excitation by at least one of a wavelength and band of wavelengths, said apparatus comprising:a viewing chamber receiving the at least one biological sample and providing a plurality of focal regions therefor;a plurality of light sources configured to emit light, one of sequentially, simultaneously, and substantially simultaneously, toward a substantially identical focal region of said plurality of focal regions in said viewing chamber on said at least one biological sample; anda plurality of optical detectors in optical relationship with said plurality of light sources, respectively, and detecting a plurality of sample light emitted from said at least one sample responsive to the light emitted from the substantially identical focal region of said at least one biological sample.
