Findings from Jiangnan University Reveals New Findings on Materials Research

February 25, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Materials Research. According to news originating from Jiangsu, People's Republic of China, by VerticalNews correspondents, research stated, "A DNAzyme-based sensor for the determination and quantification of lead ions (Pb2+) has been established, which combines the recognition and catalysis of DNAzyme with the optical properties of nanomaterials. Circular dichroism (CD) signals were obtained by a DNAzyme-based assembly of asymmetric silver nanoparticle (AgNPs) dimers."

Our news journalists obtained a quote from the research from Jiangnan University, "A good linear relationship between CD signals and Pb2+ concentration was obtained ranging from 0.05 ng.mL(-1) to 10 ng.mL(-1) with a limit of detection (LOD) of 0.02 ng.mL(-1). The specificity of this sensor in lead ion detection was excellent, and a satisfactory recovery was obtained in the analysis of tap water samples."

According to the news editors, the research concluded: "The proposed technique possesses both high sensitivity and good specificity, giving it great potential for the analysis of Pb2+ in water."
