Carbon–based materials are widely applied for sensor applications due to their extraordinary properties, like biocompatibility, inertness, wide potential window, and high electrocatalytic activity. Both graphene and carbon nanotubes are allotropes of carbon. They demonstrate excellent properties, including electrical conductance, strength, thermal, and interesting optical properties. Graphene and carbon nanotube–based materials are favorable candidates for the fabrication of sensors and biosensors at the nano–scale level. Both materials having high conductivity and high surface area, thus graphene and carbon nanotube–based sensors and biosensors perform well individually or as composites with other nanomaterials. They have the uniqueness of sensitivity, selectivity, long–term stability, rapidness, low detection limits, and good accuracy, which are the desirable properties of good sensors. So, they find uses in Surface Enhanced Raman Spectroscopy (SERS) sensors, electrochemical sensors, fluorescence sensors, and Field–Effect Transistors (FETs) sensors for biomolecules and drugs. This chapter deals with the applications of graphene and carbon nanotubes as sensors and biosensors for biomolecule and drug detection. It will be helpful to the reader in terms of the current scientific progress of graphene and carbon nanotube-based sensing and bio–sensing. This chapter will also describe the scientific research, theory, materials, and sensors/devices developed using the graphene and carbon nanotubes
