Paper Abstract

A 32-analyte integrated optical immunofluorescence multisensor system has been realized and tested for the first time. The sensor system is based upon bio/immuno-chemistry at the waveguide surface and fluoroimmunoassay in the evanescent fields of the optcal waeguides, to enable rapid, simultaneous and high-sensitivity fluorescence detection of up to 32 pollutants in water, and automatic regeneration for immediate reuse. The system has been demonstrated for estrone and a detection limit of 13 ng/L has been achieved.
