Abstract: A novel electrochemical sensor for dicyandiamide (DCD) recognition and detection was fabricated by using molecularly imprinted polymer (MIP) technique. The MIP sensor was electropolymerized on the surface of a golden electrode via cyclic voltammetry (CV). The properties of the MIP sensor were characterized via CV and differential pulse voltammetry (DPV) by using potassium ferricyanide/potassium ferrocyanide as an electroactive probe. The results showed that the response peak current was linearly related with DCD concentrations from 0.01 μmol/L to 4 μmol L-1 and a limit of detection of 0.3 nmol L-1 (S/N = 3). The sensor was satisfactorily employed to monitor the infant formula.
