Molecular imprinting is a technique with the characteristic of selective molecular recognition, which is a kind of polymer-function material made of template, functional monomers and crosslinking agent. It is widely applied for detection of pesticide residues because of specificity recognition, predetermination and practicability. This paper summarized the basic theories and the preparation of molecular imprinting polymers, and reviewed its application in the determination of pesticides residues, such as solid phase extraction, stationary phase of chromatography, solid phase microextraction, molecular imprinted membrane, sensor and so on. Furthermore, the prospect was put forward. In recent years, with the development of molecular imprinting technology combining with magnetic molecules, nanomaterials, fluorescent molecules, sensors and other application technology, it is expected to achieve a breakthrough of rapid detection technology based on high sensitivity of molecular imprinting technology, to solve the existing shortcomings such as limited varieties of pesticide measure instruments, high false-positive and hard quantitative, and then truly achieve high-throughput rapid trace detection.
