Abstract
The invention provides a method for preparing a clenbuterol hydrochloride molecularly imprinted membrane electrochemical light emitting sensor. The method is characterized in that the surface of a glassy carbon electrode is wrapped by a composite film, and the composite film consists of reduced oxidized graphene, upconversion nanoparticles and molecular imprinting polymers. The method has the advantages that electrochemical light emission of the upconversion nanoparticles with stable cathode signals and high light emission strength are combined with the molecular imprinting polymers with goodselectivity, and trace detection on clenbuterol hydrochloride in animal derived foods can be implemented.
Description
technical field The invention belongs to the technical field of preparation of photoelectrochemical sensing materials, and in particular relates to a preparation method of a clenbuterol hydrochloride molecularly imprinted film electrochemical luminescence sensor based on upconversion nanoparticles. Background technique Due to the advantages of large Stokes shift, stable fluorescence signal, low toxicity, and good biocompatibility, upconversion nanoparticles are widely used in the field of optical sensors. But there are few reports in the field of electrochemiluminescence. As a new type of electrochemiluminescent material, upconversion nanomaterials have stable cathode signal and high electrochemiluminescence intensity, and have broad application prospects in the field of electrochemiluminescence. Molecularly imprinted polymers have high selectivity and affinity, are simple to prepare, low in cost, and can specifically recognize analyte substances. They can be introduced int...
