Investigators from Shaanxi Normal University Target Chemiluminescence

June 20, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators publish new report on Chemiluminescence. According to news reporting originating in Xi'an, People's Republic of China, by NewsRx journalists, research stated, "We found that after silver nanoparticles (AgNPs) aggregated, its catalytic activity on luminol CL reaction obviously changed, and the change characteristic was closely related to the sizes of AgNPs."

The news reporters obtained a quote from the research from Shaanxi Normal University, "UV-visible spectra, X-ray photoelectron spectra, zeta potential and transmission electron microscopy studies were carried out to investigate the CL effect mechanism. The different CL responses of aggregated AgNPs with different size were suggested to be due to the two effects of quantum size and electron density in nanoparticle's conduction bands, and which one played a major role."

According to the news reporters, the research concluded: "The poisonous organic contaminants such as anilines, could induce the aggregation of AgNPs, were observed to affect effectively the luminol-H2O2-7 nm and 15 nm AgNPs CL systems and were detectable by use of a flow injection method with the enhanced or inhibited CL detection."
