Graphene-based transistors could soon help diagnose genetic diseases. Researchers in India and Japan have developed an improved method for using graphene-based transistors to detect disease-causing genes.


Researchers in India and Japan have developed an improved method for using graphene-based 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…
