  • Patent number: 10107787
    Abstract: A testing element, and methods of use therefor, for the detection of target analytes, for example metal ions and other environmental hazards, utilizing ligand functionalized fluorescent nanoparticles on a substrate. The non-toxic, air, and water stable 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 nanoparticles can be synthesized that emit over a large range of the visible spectrum. Charge transfer between a target analyte 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. The test element can have more than one type of functionalized fluorescent nanoparticle which allows for the detection of multiple target analytes using a single test element.
