  • Abstract
    This paper presents a novel design to control defect sites and to enhance sensitivity in graphene-based pH and biological sensors. We showed that pristine graphene was not sensitive to the pH. We demonstrated that the pH sensitivity of graphene could be controlled by varying the patterns and lengths of edges that were created using simple processes of photolithography and dry etching.
