New Peroxidases Study Findings Have Been Reported by Researchers at Shaanxi Normal University

By a News Reporter-Staff News Editor at Health & Medicine Week -- Data detailed on Enzymes and Coenzymes have been presented. According to news reporting out of Xi'an, People's Republic of China, by NewsRx editors, research stated, "In this study, it was found that horseradish peroxidase (HRP)-mimicking DNAzyme could effectively enhance the CL emission of CdTe quantum dots (QDs)-H2O2 system, whereas HRP could not enhance the CL intensity. The CL enhancement mechanism was investigated, and the CL enhancement was supposed to originate from the catalysis of HRP-mimicking DNAzyme on the CL reaction between CdTe QDs and H2O2."

Our news journalists obtained a quote from the research from Shaanxi Normal University, "Meantime, compared with CdTe QDs-H2O2 CL system, H2O2 concentration was markedly decreased in QDs-H2O2 HRP-mimicking DNAzyme CL system, improving the stability of QDs-H2O2 CL system. The QDs-based CL system was used to detect sensitively CdTe QDs and HRP-mimicking DNAzyme (as biologic labels)."

According to the news editors, the research concluded: "This work gives a path for enhancing CL efficiency of QDs system, and will be helpful to promote the step of QDs application in various fields such as bioassay and trace detection of analyte."
