Dual fluorescence and electrochemical detection of the organophosphorus pesticides-Ethion, malathion and fenthion

► Two sensor molecules have been designed that distinguish between the organophosphorus pesticides - fenthion, malathion and ethion. ► The organophosphorus pesticides result in a change in the fluorescence and electrochemical properties of the sensors, unique to the specific pesticide. ► The ability of each sensor to produce both fluorescence and electrochemistry allows minimization of false positives.
