An overview on the progress in the organophosphorus hydrolase based electrochemical sensors
design and application for direct organophosphorus pesticides quantification is presented in this
work. The key analytical performances of the enzyme and of the bacterial potentiometric and amperometric
organophosphorus hydrolase based sensors, as well as their advantages and deficiencies are
commented in detail.
Keywords: Electrochemical biosensors, organophosphorus hydrolase, organophosphorus pesticides.
