Abstract: Graphene presents boundless potential in transforming the way conventional electronics are made. Prior to its full-fledged implementation in industries such as semiconductor and biomedical, several bottlenecks have to be overcome such as the controlled synthesis of graphene to achieve high yield production of high quality graphene sheets and the fundamental understanding of the interface between biological entities and graphene. The work involved in this dissertation therefore relates to these two points and is broadly divided into two sections, namely the chemical routes to exfoliated graphene sheets and the fabrication of graphene biohybrid devices for protein and cellular sensing. By controlled intercalation and oxidation of graphite and careful gradient separation, we obtained highly conducting exfoliated chemically processed graphene sheets useful for flexible electronics. By interfacing graphene with biomimetic membranes and diseased cells, we studied the interfacial interaction between biotic and abiotic systems and developed useful graphene biohybrid devices for disease detection.
