Glioblastoma multiforme (GBM) is an aggressive form of malignant brain cancer. The American Association of Neurological Surgeons estimates that GBM causes 52 percent of primary brain tumors and 17 percent of primary plus metastasized brain tumors. More than 20,000 primary brain tumors are diagnosed in the United States each year, so improved treatment and monitoring of brain cancer is a critical medical need. New research from Vikas Berry and Ankit Mehta and colleagues at the University of Illinois at Chicago discovered a powerful new tool that might be able to help fill this need—sheets of carbon atoms called graphene.
