In recent years, graphene has become a fascinating material for many scientists because of its unique qualities. As the graphene structure is two-dimensional, and its carbon is sp2 hybridized arranged in a hexagonal lattice. Due to this, graphene derivatives (GO: graphene oxide and rGO: reduced graphene oxide) have been increased so much, which provides better capabilities for synthesizing graphene-based useful materials for numerous applications such as mechanical, electrical, thermal, and sensors. In this chapter, we discuss the graphene properties and their application as sensors. Also, the investigations of the stretchable matrix of graphene consist for various applications such as inflexible composite electrodes of carbon nanotubes (CNTs) and conductive hydrogel’s have utility in stretchable electroluminescent (EL). This chapter also describes that graphene is used in several sensing technologies due to its unique properties. In previous years, different platforms of sensing were given with pristine and derived graphene with nanoparticles and polymers. A few of these stages were utilized to immobilize biomolecules, for example, antibodies, DNA, and proteins to make profoundly delicate and specific biosensors. Systems to connect these biomolecules onto the outside of graphene have been utilized dependent on its compound structure. Here, we summarized the research conducted that uses graphene and its derivatives to produce valuable biosensors by combining with DNA molecules and antibodies, which is ready to recognize and distinguish an assortment of sicknesses, microorganisms, and biomolecules connected to diseases. |
