摘要： An electrochemiluminescence (ECL) switch sensor with a dual-recognition mechanism was developed based on complexation reactions and a molecular imprinted film (MIP). The MIP was prepared on a gold electrode with ferroferric oxide/carbon quantum dots (Fe3O4/C-dots) via electrochemical polymerization. An L-canavanine trinitrobenzene complex was used as the template molecule and o-phenylenediamine was used as the functional monomer. Further, C-dots were used as the ECL signal elements and the L-canavanine-trinitrobenzene complex could quench the ECL signal. Subsequently, by using the elution and re-adsorption of the template molecule as the control switch, it was possible to control the ECL intensity of the sensor, and establish a new method for rapidly measuring L-canavanine. A sensor that combined complexation recognition and imprinting recognition demonstrated excellent performance in terms of recognizing specific target :molecules. The detection limits of this method reached 7.32 x 10(-11) mol L-1, and the measurement results for practical samples were satisfactory.
