Abstract
This chapter reviews the usage of graphene nanostructures in the fabrication
of electrochemical sensors. In current ages, graphene derivatives have attracted a great
deal of attention due to their outstanding electrical, mechanical, and thermal properties,
making them one of the most popular choices to develop the electrodes of a sensor. In
addition, the high effective surface area, electrocatalytic activity, excellent electrical
conductivity, high porosity and adsorption capability, fascinating their electrochemical
properties, which turn them as potential candidates for electrochemical applications,
particularly sensing. This chapter deals with an overview of the work done on
graphene-based nanocomposites in very recent years. It explains the properties of
graphene-based nanocomposites for their usage as electrochemical sensors.
Keywords: Electrochemical sensor, Graphene, Nanocomposite
