Graphene Field-Effect Transistors: Advanced Bioelectronic Devices for Sensing Applications

Carbon-based nanomaterials, particularly graphene, have a wide range of applications in various fields due to their unique properties such as high carrier mobility, adjustable bandgap, tunable conductance, quantum Hall effect, high capacity, and ambipolar field effect. In particular, graphene has been utilized in the bioelectronics fields such as disease diagnosis, infectious pathogen detection, and environment monitoring. Recently, graphene-based bioelectronics was developed by the receptors (bio/chemical) conjugation onto graphene, its applications were diverse following electronic sense, biomedical, etc. In this chapter, graphene-based bioelectronics and its applications are introduced.
