Fabrication and Characterization of Hybrids with Graphene Derivatives/Analogues for Analytical Applications

Nanomaterials are the materials with size ranging from 1 to 100 nm in any one dimension. They are classified into metal, metal oxide, semiconductor and carbon nanomaterials. They exhibit remarkable properties when compared to their bulk counterparts. Nanotechnology is an application-oriented field and is applied in multi-disciplines. Instead of using as single nanomaterials, when hybridized with one or two other nanomaterials, they show extraordinary performance. Graphene is a two-dimensional material which is exfoliated as a single layer from the multiple stacked layers of graphite. Its derivatives are available in the form of graphene oxide and reduced graphene oxide. Graphene is regarded as wonder material because of its properties such as large surface area, high electrical conductivity, high thermal conductivity, high strength, light weight, highly anticorrosive and more sensing ability. Hybrids of Graphene Derivatives harvest the benefits of graphene to explore the applications of graphene in many fields. Sensors are the devices used to measure various analytes like physical quantities, chemicals and biomolecules in terms of the transduction mechanisms such as electrical, electrochemical and optical parameters. In this chapter, synthesis and characterization of Hybrids of Graphene Derivatives and their sensing performance are discussed.
