▎ 摘  要

NOVELTY - A construction method of a molecularly imprinted copper metal organic framework (CuMOFs) electrochemical sensor based on a copper ferricyanide signal probe, involves preparing a magnetic molecularly imprinted (MMIP)-CuMOFs by an in-situ self-assembly method, then using a copper ferricyanide generated by the reaction of copper ion (Cu2+) and potassium ferricyanide in MMIP-CuMOFs as a signal probe to construct an electrochemical sensor. USE - Construction method of a molecularly imprinted CuMOFs electrochemical sensor is used for detecting the detection linear range of bisphenol A, which is 0.5-500 nmol/L, and the detection limit, which is 0.38 nmol/L (claimed), and harmful substance in food. ADVANTAGE - The method uses in-situ self-assembly method to prepare MMIP-CuMOFs, the metal organic framework material is combined with the molecular imprinting technology to improve the ability of the sensor to quickly and specifically identify the object to be detected. The sensor realizes high sensitivity of bisphenol A, and high selectivity detection.
