  Nanotechnology has revolutionised material science by developing novel nanomaterials with controllable morphology and physicochemical properties for diversified applications in biosensors. Among different nanomaterials, carbon-based nanomaterials (i.e. carbon nanotubes and graphene) has received a lot of attention due to unique advantages like high surface-volume ratio, excellent conductivity, chemical stability and strong mechanical strength, and are thus frequently being used as building blocks for biosensors. In this review article, a brief description of nanomaterials and biosensors are firstly presented. Then, carbon nanotubes and graphene are introduced in Sections 2 and 3, respectively, along with their applications in field-effect transistor based biosensors fabrication for label-free, real time, high sensitive, and selective detection of biomolecules in more detail. Finally, we briefly discuss the current status and future direction for further development of carbon nanotubes and graphene based biosensing devices.
