Ultrafast graphene sensor monitors your breath while you speak
Graphene is just spearheading researchers' foray into the world of two-dimensional (2D) materials.
Graphene is just spearheading researchers' foray into the world of two-dimensional (2D) materials. Besides carbon, molybdenum (MoS2), tungsten (WS2), and vanadium (VS2) all promise new material systems with unique properties and performance for a range of application areas. Functionalized graphene, for instance, holds exceptional promise for biological and chemical sensors. Now, in new work, researchers from the Nokia Research Center in Cambridge, UK, have shown that the distinctive 2D structure of graphene oxide (GO), combined with its superpermeability to water molecules, leads to sensing devices with an unprecedented speed.
