Pinning DNA-sized ribbons of carbon to a gas sensor can boost its sensitivity far better than any other known carbon material, says a new study from the University of Nebraska-Lincoln. When the researchers integrated a film of graphene nano-ribbons into the circuitry of a gas sensor, it responded about 100X more sensitively to molecules than did sensors featuring even the best-performing carbon-based materials...
