Abstract
Combining fluoroimmunoassay principles and fiber-optic fluorimetry has extended the available transduction schemes for development of fiber-optic sensors. Three representative designs are discussed focusing on a sensor configuration utilizing a controlled-release polymer to sustain a release of indicating reagents over long periods. This novel approach has been adapted for pesticide monitoring. A model system has been designed that releases the reagents of a homogeneous fluoroimmunoassay from an ethylene vinyl acetate polymer for the detection of atrazine. The sensor utilizes a competition reaction between fluorescent-labeled and unlabeled atrazine for the available binding sites on labeled anti-atrazine antibodies.
