Graphene-Based Nanocomposites in Electrochemical Sensing

The use of graphene nanocomposites in the fabrication and creation of electrochemical sensors is discussed in this chapter. Graphene derivatives have garnered significant interest in the last decades due to their exceptional electrical, mechanical, and thermal characteristics, which have made them a preferred choice in the development of sensor electrodes. Moreover, their electrochemical properties make them ideal candidates for electrochemical applications, especially in sensing due to their electrocatalytic activity, highly effective surface area, excellent electrical conductivity, adsorption capability, and high porosity. Over the past few years, there has been significant progress in the development of graphene-based nanocomposites. This chapter aims to provide an overview of these works and their findings for those with prior knowledge of the subject matter. Also, it elucidates the characteristics of graphene nanocomposites and their potential use as electrochemical sensors.
