A novel cross-linker maleic rosin acrylic acid glycol ester for preparing highly sensitive,molecularly imprinted electrochemical sensors was proposed for Quercetin(Qu) determination.A Molecularly Imprinted Polymer(MIP) film was created on a glassy carbon electrode using free radical polymerization method.The modification procedure was characterized via electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV).
