Back in 2004, Andrew Geim and Konstantin Novoselov discovered graphene, and within just a few years medtech engineers were gaga for graphene. Graphene is a one-atom-thick sheet composed of carbon arranged in a hexagon or honeycomb-like lattice. Today the material is used in a wide array of medical applications and it seems scientists are still uncovering new properties of the wonder material. Most recently, researchers at the Massachusetts Institute of Technology (MIT) and their colleagues at other universities discovered an unexpected electronic property of graphene. The MIT-led work, which involves structures composed of atomically thin layers of materials that are also biocompatible, could usher in new, faster information-processing paradigms. One potential application is in neuromorphic computing, which aims to replicate the neuronal cells in the body responsible for everything from behavior to memories.
