  • Crumpled graphene makes ultra-sensitive cancer DNA detector

    In this computer simulation, DNA in a serum sample interacts with a crumpled graphene surface.

    Illinois researchers found that crumpling graphene in DNA sensors made it tens of thousands of times more sensitive, making it a feasible platform for liquid biopsy.
