By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Proteins are discussed in a new report. According to news originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "In this paper, we reported a facile method of fabricating a reusable fluorescent Cu(2+)-sensor. To fabricate the reusable sensor, the bovine serum albumin-protected gold nanoclusters (BSAGNCs) were complexed with polyelectrolytes, i.e., positively charged polydiallyldimethylammonium (PDDA) and negatively charged polystyrenesulfonate (PSS), and were coated on a glass slide."
Our news journalists obtained a quote from the research from the University of Science and Technology, "The prepared film-modified glass slides exhibited the recyclability of fluorescent signal 'off-on' behaviors: the fluorescence could be switched 'off' by immersing the film sensors in Cu(2+) solution and 'on' by washing with ethylene diamine tetraacetic acid (EDTA) solution. The prepared film-modified glass slides exhibited high selectivity towards Cu(2+) the fluorescence quenching behavior in the form of the Stern-Volmer equation. In addition, the spiked tap water samples were analyzed with satisfactory results."
According to the news editors, the research concluded: "These demonstrations provide a new convenient approach to develop the BSAGNCs-based, reusable fluorescence sensors."
