Investigators at Tsinghua University Report Findings in DNA Research

May 20, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on DNA Research is now available. According to news originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "A, multiplex DNA assay based on nanoparticle (NP) tags detection utilizing single particle mode inductively coupled plasma mass spectrometry (SP-ICP-MS) as ultra-sensitive readout has been demonstrated in the article. Three DNA targets associated with clinical diseases (HIV, HAV, and HBV) down to 1 pM were detected by DNA probes labeled with AuNPs, AgNPs, and PtNPs via DNA sandwich assay."

Our news journalists obtained a quote from the research from Tsinghua University, "Single nucleotide polymorphisms in genes can also be effectively discriminated. Since our method is unaffected by the sample matrix, it is well-suited for diagnostic applications."

According to the news editors, the research concluded: "Moreover, with the high sensitivity of SP-ICP-MS and the variety of NPs detectable by SP-ICP-MS, high-throughput DNA assay could be achieved without signal amplification or chain reaction amplification."
