In this study,a rapid sensitive fluorescent method for the detection of aflatoxin B_1( AFB_1)was developed based on BSA-gold nanoclusters( AuNCs). The method combined the interaction of Au+and Hg~(2+),leading to the fluorescence quenching of Au NCs,and the chelation of Hg~(2+)with AFB_1,leading to the fluorescence recovery of Au NCs. In the optimal conditions,this method obtained a detection limit of 0. 1 ng/m L with a linear range of 0. 1-10 ng/m L. The above method was applied to detect AFB_1 in rice samp...
