Researchers, led by Robert Hurt, professor of engineering, have found that a simple technique can swathe nanoparticles with a blanket of graphene, which could carry medical imaging contrast agents, allowing the nanoparticles to enhance imaging signals while shielding tissue from their potential toxic effects. They could also deliver chemotherapy drugs to tumors.
