Electropolymerized molecular imprinting on gold nanoparticle-carbon nanotube modified electrode for electrochemical detection of triazophos

► An electrochemical sensor for pesticide triazophos is prepared by electropolymerized molecular imprinting film onto the AuNP/CNT/GC electrode surface. ► The sensor can effectively improve the reductive properties of triazophos and eliminate interferences of other pesticides. ► In addition, the AuNPs can strikingly amplify the electrochemical response of triazophos and improve the sensitivity to triazophos.
