6-Chloro-N,N-Diethyl-1,3,5-Triazine-2,4-Diamine (Simazine) Electrochemical Sensing Chip Based on Biomimetic Recognition Utilizing a Molecularly Imprinted Polymer Layer on a Gold Chip

Abstract

Electrochemical sensing chip of 6-chloro-N,N-diethyl-1,3,5-triazine-2,4-diamine (Simazine) was developed on its reductive current. In order to give sensitivity and selectivity to the simazine sensing chip, a gold chip was modified with molecularly imprinted polymer (MIP) for simazine, which is worked as biomimetic recognition element and showed. Using simazine sensing chip, cathodic current of simazine was measured by cyclic voltammetry and the peak current depended on the concentration of simazine. The detection limit was 0.4 µM. Simazine sensing chip was 29 times more sensitive to simazine than bare gold electrode and showed selective response to simazine compared to atrazine and MCC, by the modification with Sim-MIP.
