摘　　要：In this study,a water-soluble fluorescent probe based on copper nanoparticles(CuNPs)was synthesized using a hydrothermal method with bovine serum albumin(BSA)(BSA@CuNPs)as a protectant,and it was utilized to efficiently detect the concentration of tetracycline(TC).Upon the addition of TC to the BSA@CuNPs probe,its fluorescence intensity is obviously diminished due to the keto-enol functions C=O group in TC connects with the hydroxyl group on the BSA@CuNPs probe to form a non-fluorescent complex,which can be successfully utilized for detecting TC concentration.Linear range and detection limit for TC detection are 0.1130μM and 90 nM.Furthermore,the BSA@CuNPs probe was applied to detect TC concentrations in real meat samples,with recoveries ranging from 95.40%to 102.13%,and the relative standard deviation(RSD)was below 2.73%.Therefore,BSA@CuNPs probe exhibits high sensitivity and selectivity for TC,which will be used for the study of TC analysis in meat.
