Abstract
Clenbuterol (CLB), a member of β-agonist family, has now been a serious threat to human health due to its illegal usage in the animal feed. In this paper, we designed a fluorescence resonance energy transfer (FRET) system consisting of carbon dots (C-dots) and gold nanoparticles (AuNPs) for recovered fluorescence detecting of CLB. In the presence of CLB, CLB molecules can interact with AuNPs via Au-N bonds, preventing the interaction of C-dots and AuNPs, which induced the recover of the fluorescent intensity. Under the optimal conditions, the limit of detection for CLB was 3 nM, with a wide concentration linear range of 8-200 nM (S/N = 3). Meanwhile, the proposed method was successfully applied to detect CLB in pork samples, illustrating it could be used as a reliable, rapid, and cost-effective method for the determination of CLB residues in pork samples.Entities:
