제목 Graphene meshes for biological sensor applications
초록 Graphene has drawn great interest as a promising platform for novel electronic systems. For instance, graphene has been intensively studied for use in sensors because its charge carrier transport is sensitively affected by the surrounding chemical and biological environment. However, the sensing characteristics of graphene devices have varied from case to case, and its mechanism has not been satisfactorily determined thus far. Here we describe a silica-assisted chemical vapor deposition (CVD) technique that can directly synthesize graphene meshes (GMs). The resulting GMs have a circular hole array and nearly ideal edges, and thus can be exploited as a platform to study the intrinsic response of defects to gaseous and ionic molecules, as well as biological species. Particular interests will be paid on the defect mediated molecular interaction and charge transfer and their effects on the sensitivity and reliability of the graphene-based chemical and biological sensors.
