Abstract

Recently, carbon-based nanomaterials (CBNM) have been widely used for chemical and biosensing applications due to their outstanding physicochemical properties, such as mechanical, thermal, optical, electrical and structural diversity. Such materials include carbon nanotubes, graphene oxide, graphene quantum dots and fullerene. As a consequence of inimitable features, these give superior strength, electrical conductivity, and flexibility toward numerous chemical and biological objects, which is valuable for chemical sensing and biosensing purposes. However, the specific intrinsic property makes graphene and carbon nanotubes (CNTs) most attractive among the various allotropes of carbon. Since the environmental contaminants in ppm level affect the people, therefore the use of CBNM for environmental sensing provides an accessible cache of data for modelling, which makes it easy to monitor environmental challenges. Thus, the biological, chemical, thermal, stress, optical, strain and flow sensors deliver a larger surface area, excellent electrical conductivity with chemical constancy, as well as mechanical difficulty with straightforward functionalization pathways of CNTs to improve old-style carbon electrode sensor platforms. Therefore, in this chapter, the CBNM for sensing purposes are focused in detail on their mechanism.
