摘要： Chloramphenicol (CAP) is a once widely used antibiotic, which is able to cause great harm to human health, is banned in some countries or organizations such as China, USA and the European Union for animal breeding. Because CAP in pig hair degraded slower and had amount of residues, pig hair could be used as the target to detect CAP residues. In this study, a competitive lateral flow immunoassay (LFIA), whose label was aggregation induced emission fluorescent nanobeads (AIEFN), was firstly developed for the detection of CAP in pig hair samples. It exhibited a low limit of detection (0.001 mu g/kg) and a broad linear range (0.0025-0.32 mu g/kg). The recovery rate and coefficient variation with spiked pig hair samples were 88.50%-106.17 % and 1.01%-7.37 %, which indicated good accuracy of this assay. The result of AIEFN-LFIA for the detection of CAP in pig hair was consistent with that of liquid chromatography-mass spectrometry. This assay was rapid with the total detection duration of about 20 min. AIEFN-LFIA was able to be used for rapid, sensitive, accurate and convenient detection of CAP residues in pig hair samples.
