Abstract:
Since the discovery of graphene, it has drawn significant attention in many different research or application fields due to its extraordinary electrical and optical properties. As a two-dimensional material, both graphene's electrical and optical properties can be dramatically modified due to small perturbations from the surrounding environment. Therefore, graphene has great potential as active medium for versatile and sensitive sensors. Early studies have demonstrated excellent sensitivity of graphene field-effect transistor for gas molecule sensing and action potential detection. As will be shown in this presentation, graphene optical sensor can also be designed to have good sensitivity and enables new possibilities of optical spectroscopic measurement as well as opto-electronic studies. With the versatility of graphene, we show that graphene provides a great platform for electrochemical optical sensing as well as opto-electronic sensor in bio-electric detection.
