Abstract： The problem of drug residues caused by the wide use of norfloxacin in livestock，poultry and aquaculture is becoming increasingly serious，which puts forward higher requirements for detection technology. Quantum dot technology has become a key means to construct new detection systems due to its excellent fluorescence properties，good interface modifcation ability and structural controllability.This paper systematically reviews the quantum dot detection methods based on immune recognition， aptamer recognition and molecular imprinting mechanisms，compares their differences in construction methods，types of adapted samples and detection performance，and analyzes their applicability in rapid screening ofcomplex matrices，aiming to provide atheoretical basis and technical reference for the rapid detection of small molecule drug residues in animal-derived foods.
