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...

Scientist’s accidental exhale leads to improved DNA detector

Greg Madejski held his breath as he looked into the microscope, trying to weld two fingernail-sized chips together: a tiny chip containing a nanofilter on top of another chip with a DNA sensor. It was frustrating work. The chips weren’t making good contact with each other. Madejski gently poked at the chips, then peered over...
