Findings from Hunan University Provide New Insights into Nanoparticles [Poly(thymine)-templated Fluorescent Copper Nanoparticles for Ultrasensitive Label-free Detection of Pb2+ Ion]

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Nanoparticles. According to news reporting originating in Changsha, People's Republic of China, by NewsRx journalists, research stated, "Polythymine (poly T)-templated copper nanoparticles (CuNPs) were demonstrated as novel and sensitive fluorescence probes for the detection of Pb2+ based on the fluorescence quenching effect. The as-prepared CuNPs displayed strong fluorescence emission."

The news reporters obtained a quote from the research from Hunan University, "However, the fluorescence of CuNPs was readily quenched in the presence of Pb2+. These changes in fluorescence intensity of CuNPs allowed for the analysis of Pb2+ with rapidity (

According to the news reporters, the research concluded: "We validated the practicality of using CuNPs for the determination of Pb2+ in environmental samples through analyses of tap water samples."
