Copper nanocluster-based fluorescent probe for sensitive and selective detection of Hg(2+) in water and food stuff.

In this study, Hg(2+) ions were found to quench the fluorescence of glutathione (GSH)-capped copper clusters (Cu NCs). The Cu NCs were prepared by a simple reduction of CuSO4 in the presence of GSH serving both as a reducing and protecting agents, and characterized by ultraviolet-visible absorption spectroscopy (UV-vis), high resolution scanning electron… CONTINUE READING
