Improving DNA-Detecting Transistors
Tsukuba, Japan, Feb 24, 2017 – (ACN Newswire) – Researchers in India and Japan have developed an improved method for using graphene-based transistors to detect disease-causing genes.
Graphene field-effect transistors (GFETs) can detect harmful genes through DNA hybridization, which occurs when a ‘probe DNA’ combines, or hybridizes, with its complementary ‘target DNA.’ Electrical conduction changes in the transistor when hybridization occurs.
Nobutaka Hanagata of Japan’s National Institute for Materials Science and colleagues improved the sensors by attaching the probe DNA to the transistor through a drying process. This eliminated the need for a … Read More → "Improving DNA-Detecting Transistors"
