	1	Analysis of penicillamine using Cu-modified graphene quantum dots synthesized from uric acid as single precursor显示文摘A simple methodology was developed to quantify penicillamine(PA) in pharmaceutical samples, using the selective interaction of the drug with Cu-modified graphene quantum dots(Cu-GQDs). The proposed strategy combines the advantages of carbon dots(over other nanoparticles) with the high affinity of PA for the proposed Cu-GQDs, resulting in a significant and selective quenching effect. Under the optimum conditions for the interaction, a linear response(in the 0.10–7.50 μmol/L PA concentration range) was observed. The highly fluorescent GQDs used were synthesized using uric acid as single precursor and then characterized by high resolution transmission electron microscopy, Raman spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, fluorescence, and absorption spectroscopy. The proposed methodology could also be extended to other compounds, further expanding the applicability of GQDs.
