Abstract: Animal derived foods containing veterinary drugs, microbial toxins, preservatives, and drug residues during food processing can cause significant toxic effects and allergic reactions, posing a threat to human health.Molecular imprinting technology mainly induces templates to form specific recognition sites in polymers, which has advantages such as predictability, recognition, and practicality, and has played an important role in the field of veterinary drug residue detection.The robustness, high affinity, specificity, and low production cost of polymer receptors prepared using molecular imprinting technology make them an alternative to natural receptors and toxic compounds.By combining molecular imprinting technology with sensor technology, the advantages and characteristics of both can be fully utilized.The progress of polymer science and nanotechnology can help improve the performance of molecular imprinted polymer sensors, and the applicable fields of molecular imprinted sensors are further expanded.In recent years, many high-quality literature has reported on the research of molecularly imprinted polymer sensors in the fields of biomolecules, abused drugs, and explosives, promoting the application of this technology in the fields of life sciences and hazardous chemicals.The author focuses on the principles of molecular imprinting technology and molecular imprinting sensors, and introduces the latest achievements of sensor technology based on molecular imprinted polymers, as well as research in the field of veterinary drug residue detection applications.

Key words: molecular imprinting; molecularly imprinted polymer; molecular imprinting sensor; veterinary drug residue
