Electrochemical sensors are among the most explored microsensors because of their versatility and portability. They depend on measuring the redox reaction between an analyte in the electrolyte and a working electrode. In recent years, carbon composites have received the attention of researchers within the general expansion of electrochemistry-based sensing technology. Carbon composite materials include graphite, graphene, carbon nanotubes, carbon fibres, nanoribbons, graphene oxides, glassy carbon, graphite reinforced polymers etc. They have properties which allow them to perform as an excellent electrode material for the development of sensing devices as they permit rapid electron transfer with absorbed molecules.
