The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in my group focuses on two fundamental aspects that need to be characterized in order to use graphene as an ideal sensor material: i) how to effectively interface graphene devices with biological materials so that detection becomes sensitive and selective, and ii) understand and characterize the chemical reactivity of ‘just made’ graphene edges. Exploiting the full potential offered by graphene as a natural material in sensing applications will only be possible through in-depth fundamental research of these two limiting aspects.
