Paper Abstract

Different sensing systems suitable for the determination of pesticides, metals and chlorinated organic compounds are described. The systems are based on the use of conjugated polymers and biological components that are sensitive to compounds commonly used as pesticides, chlorinated phenoxy herbicides or industrial chemicals. Biological molecules were immobilized on various carriers and were integrated in multiarray formats or in automated flow-through systems. This work describes the synthesis and characterization of polymers, biological conjugates and metabolites for the detection of a range of toxic chemicals, including chlorinated phenols, s- triazine herbicides, polychlorinated biphenyls, and heavy metals. The characteristic features of the different formats are given including a new promising approach for heavy metal detection using o-hydroxypyridylazo metal-protein conjugates.
