By a News Reporter-Staff News Editor at Science Letter -- Research findings on Nanoparticles are discussed in a new report. According to news originating from Seoul, South Korea, by NewsRx correspondents, research stated, "A highly sensitive colorimetric sensing platform for the selective trace analysis for Co2+ ions is reported, based on glutathione (GSH)-modified silver nanoparticles (AgNP). The shape of metallic nanoparticles used in colorimetric detection, using the unique optical properties of plasmonic nanoparticles, is almost spherical."
Our news journalists obtained a quote from the research from Kwangwoon University, "Therefore, in this work we attempted to investigate the selective detection of heavy metal ion (Co2+), with the shape of AgNPs (nanosphere, nanoplate, and nanorod). GSH-AgNP with spherical shape shows a high sensitivity for all of the metal ions (Ni2+, Co2+, Ce2+, Pb2+, and As3+) but poor selective recognition for target metal ions. Whereas, AgNPs solution containing rod-type GSH-AgNP has a special response to Co2+, and its selective detection might be based on the cooperative effect of CTAB and GSH."
According to the news editors, the research concluded: "Therefore, Co2+ ion could be selectively recognized using rod-type GSH-AgNPs."
