Application of nano-based electrochemical sensor in veterinary drug residue detection

With the continuous improvement of the quality of life, people pay more and more attention to the safety of animal food. Excessive veterinary drug residues in animal products can cause harm to the human body, and the research progress of detection technology in food has become the focus of attention. Electrochemical detection technology has the advantages of high sensitivity, low detection limit, easy to use, and fast detection. As a modified material, nano-based can provide more binding sites for electrochemical detection, and obtain more sensitive current response signals and higher detection efficiency. Nanomaterials are widely used in the detection of veterinary drug residues because of their excellent catalytic and conductive properties and excellent affinity for the substance to be tested. This work reported the types of veterinary drugs, relevant regulations for use, and the hazards of adding veterinary drugs. The application status of electrochemical sensors modified by carbon, metal particles and quantum dots in the detection of veterinary drug residues in food are mainly introduced. Finally, the development prospects of electrochemical sensors in the detection of veterinary drug residues are discussed.
