According to a November 14 news release from Penn State University, researchers have paved the way for a new gene sequencing technique that is based on threading the 3 billion letter-long DNA sequences unique to each and every human through a tiny hole and using a nearby sensor to read each letter as it passes through.
The new DNA sensor uses graphene, a lattice of carbon roughly the thickness of an atom. While earlier iterations of the technique leveraged graphene’s unparalleled thinness, the University of Pennsylvania research team shows how the Nobel Prize-wining material’s unique electrical properties may be used to produce faster and more sensitive gene sequencing machines.
