Researchers at Beijing University of Chemical Technology Release New Data on Gold Nanoparticles

June 17, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Gold Nanoparticles are presented in a new report. According to news reporting originating in Beijing, People's Republic of China, by NewsRx journalists, research stated, "In this work, we utilized the nonionic fluorosurfactant-capped gold nanoparticles (GNPs) as a novel chemiluminescence (CL) probe for the determination of trace bisphenol A. Bisphenol A can induce a sharp decrease in CL intensity from the GNP-Co2+-peroxymonocarbonate (HCO4-) system. Under the selected experimental conditions, a linear relationship was obtained between the CL intensity and the logarithm of concentration of bisphenol A in the range of 0.05-50 mu M (R-2 = 0.9936), and the detection limit at a signal-to-noise ratio of 3 for bisphenol A was 10 nM."

The news reporters obtained a quote from the research from the Beijing University of Chemical Technology, "The applicability of the proposed method has been validated by determining bisphenol A in real polycarbonate samples with satisfactory results. The recoveries for bisphenol A in spiked samples were found to be between 94.4% and 105.0%. The relative standard deviation (RSD) for 12 repeated measurements of 0.5 mu M bisphenol A was 2.2%."

According to the news reporters, the research concluded: "The proposed method described herein was simple, selective and obviated the need of extensive sample pretreatment."
