Molecular imprinting technology and its application for the detection of pesticide residue

Molecular imprinting technology refers to a technique for preparing a high molecular polymer that selectively recognizes a target molecule. The technology has the advantages of recognition specificity, high selectivity, reusability, etc., which can effectively remove matrix interference and is suitable for the detection and analysis of trace levels of substances in complex samples of matrix. Molecularly imprinted polymer is a selective adsorption material with specific recognition function, which can effectively separate the target component from the sample through its recognition function, and has unique advantages in the separation and enrichment of the target molecule. The selectivity and practicability of molecular imprinting technology make it have broad application prospects. In recent years, molecular imprinting technology has received more and more attention in the detection of pesticide residues, and has achieved good results in the detection and analysis of pesticide residues such as organophosphorus and carbamate. Based on the introduction of molecular imprinting technology, this paper summarized the important application of this method in pesticide residue detection in recent years, and prospected the development prospect of molecular imprinting technology in pesticide residue detection, in order to provide reference for the improvement and development of pesticide residue detection.
