Crumpled graphene makes ultra-sensitive cancer DNA detector

UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN, NEWS BUREAU CHAMPAIGN, Ill. — Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient’s blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it more than ten thousand times more sensitive to...
