▎ 摘　　要

In this work, the graphene quantum dots (GQDs) based fluorescent sensors for detection of clenbuterol (CLB) using the fluorescence resonance energy transfer (FRET) effect were developed and characterized. In the sensors, GQDs played as donor meanwhile the conjugated molecule formed from N-1-naphthylethylen diamine (NED) and diazonium-CLB was the acceptor. A good overlapping between the acceptor's UV-vis spectrum and donor's PL spectrum was observed. The CLB detection limit of the sensors was found at the CLB concentration of 10(-10) g/ml. A wide linearity relationship between the PL intensities of the sensors and the CLB concentrations in the range from 10(-4) g/ml to 10(-10) g/ml was observed. This report contributes to the design of GQDs based fluorescent sensor for detection of growth promoters.
