Electrochemically active functionalization of graphene for development of prototype biosensing devices

Development of low-cost, robust and ultra-sensing material platforms for clinically important analytes is one of the key steps for new-generation biosensors. As a promising 2D material, graphene has emerged to fulfill such purposes. Graphene based materials have shown the potential to be an ideal support for chemosensors and biosensors.

Functionalization of graphene can further transform this 2D material into various versatile platforms for different applications. In this presentation, we will address some of our recent investigations: (1) electrochemically active functionalization of graphene nanosheets, (2) loading of different enzymes on functionalized graphene matrix, and (3) electrochemical performances of the functionalized nanaohybrid materials based prototype sensors.

These latest advancements could be crucial for the design and fabrication of low-cost, flexible and disposable biosensors.
