Abstract:Animal products are a vital part of people's daily diet.The problem of veterinary drug residues in animal products has attracted more and more attention.Nucleic acid aptamer technology involves screening and specific recognition.The nucleic acid aptamer is a single-stranded RNA or DNA sequence，obtained by in vitro screening.Aptamer was referred to as a“chemical antibody”，which can specifically binds to a target substance.Compared with the traditional detection method，it has the advantages of short detection period，low cost，and no environmental constraints.This paper focused on animal products，based on the traditional detection methods of animal residues，reviewed the application of nucleic acid aptamers in the detection of various veterinary drug residues.At the end，the application prospects of nucleic acid aptamers in this field was prospected.
