Functionalization of Graphene using Carboxylation Process

Abstract

Graphene, the starting material for all the carbon nanostructures has attracted strong scientific and technological interest in recent years. It has shown great promise in many applications, such as electronics, energy storage and conversion (super capacitors, batteries, fuel cells, solar cells, and bioscience/biotechnologies. Graphene is a zero-gap semiconductor material, which is electroactive and transparent. Because of its interesting properties, graphene has found its way into a wide variety of biosensing schemes. It has been used as a transducer in bio-field-effect transistors, electrochemical biosensors impedance biosensors, electrochemiluminescence, and fluorescence biosensors, as well as bimolecular labels.so Functionalization and dispersion of graphene sheets are of crucial importance for their end applications. In our article, we have functionalized Graphene using carboxylation process for its application in biosensors
