The magnetic molecularly imprinted polymers(MMIPs),prepared with magnetic materials as carriers,are a class of polymers with specific molecular recognition sites.The analyte can be enriched and separated in an external magnetic field.So,applying of MMIPs can solve some problems about pretreatment of food samples,such as time consuming,separation difficulty.It can be achieved for rapid and accurate detection of pesticides,veterinary drugs and banned additives in food by combination of MMIPs with other analytical instruments.Basic preparation methods of MMIPs were summarized,and the advantages a...
