Biosensors for direct determination of organophosphate pesticides.
Direct, selective, rapid and simple determination of organophosphate pesticides has been achieved by integrating organophosphorus hydrolase with electrochemical and opitical transducers. Organophosphorus hydrolase catalyzes the hydrolysis of a wide range of organophosphate compounds, releasing an acid and an alcohol that can be detected directly. This article reviews development, characterization and applications of organophosphorus hydrolase-based potentiometric, amperometric and optical biosensors.
