Advanced Magnetic Imprinted Polymers Integrated with In Situ Ionization Mass Spectrometry for High-Throughput Pesticide Screening and Detection in Food Matrices

This research introduces magnetic molecularly imprinted polymers (MMIPs) as a novel tool for the efficient extraction and detection of pesticide residues in food products. The MMIPs exhibit a notable adsorption capacity ranging from 15.70 to 23.57 mg g−1, showcasing their efficacy in preconcentrating multiple pesticides. By leveraging Low-Temperature Plasma Mass Spectrometry (LTP-MS) in conjunction with MMIP-based sample pretreatment, the study achieves rapid screening of 108 pesticides in...
