Data on DNA Research Reported by Researchers at Vietnam National University Hanoi (Highly sensitive DNA sensor based on polypyrrole nanowire)

August 1, 2014

By a News Reporter-Staff News Editor at Science Letter -- Research findings on DNA Research are discussed in a new report. According to news reporting from Hanoi, Vietnam, by NewsRx journalists, research stated, "This paper describes the development of a DNA sensor based on polypyrrole nanowire. By using potentiostatic technique, in the presence of gelatin as the soft mold, the polypyrrole nanowires were synthesized on the surface of the micro-sensor."

The news correspondents obtained a quote from the research from Vietnam National University Hanoi, "The surface enhanced Raman spectroscopy shows that the N-H ends of the polypyrrole nanowires orientate upward from the surface facilitating the DNA probe immobilization through the simple linkage with the phosphate groups of the probe DNA. The label-free signal readout was carried out by lock-in amplifier technique. The response time of the DNA sensor is 10 s and the measurement time was 5 min."

According to the news reporters, the research concluded: "The lowest detectable concentration of Escherichia coil DNA was 0.1 nM."
