摘要： A method for the fluorescence detection of metal ions and other environmental hazards utilizing ligand functionalized fluorescent nanoparticles. Synthesis of the non-toxic, air, and water stable nanoparticles has been optimized. The fluorescent nanoparticles of the present invention are made from varying ratios of metals including zinc, silver, copper, and indium and sulfur. By varying the ratios of these metals we are able to synthesize nanoparticles that emit over a large range of the visible spectrum. Charge transfer between a target molecule and the nanoparticle is readily identified by a fluorescence change allowing for a fast, simple, visual detection system without the need for expensive analytical instrumentation.
