The efficiency of the prepared MIP electrode for the extraction of the CZ in tomato, onion, lettuce, and rice, spiked with cyanazyne, was demonstrated [44]. A molecularly imprinted electrochemical impedimetric sensor was constructed for the selective determination of melamine. The sensor consisted of a gold electrode modified by electrochemical polymerization of 2-mercaptobenzimidazole (2-MBI) using cyclic voltammetry (CV) in the presence of the template molecule melamine. 6). 001 M melamine and calibration plot.
