Abstract: Magnetic molecularly imprinted polymers (MMIPs) were prepared by the molecular imprinting technology (MIT) combined with a magnetic material. MIT was a new type of high efficient separation and molecular recognition technology, and had the specific recognition and selectivity. Magnetic materials had superparamagnetism, which could be separated from the solution under additional magnetic field fast, with their surface getting a variety of reaction functional group through the way such as copolymerization or surface modification, which could be combined with target molecules by adsorption or covalent bonds. After the combination, MMIPs had the common advantages of magnetic materials and molecularly imprinted polymer, such as specific recognition and selectivity, and could be separated fast from the solution. This paper summarized the preparation methods of MMIPs and their advantages and disadvantages, and the application of MMIPs in the analysis of pesticide residues, biological medicine residues and veterinary drug residues in foods.
