Electrochemical Sensors Based on Carbon Composite Materials

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. They have been found to enhance the response time, versatility and sensitivity of sensors over traditional electrode materials, they are particularly regarded as suitable matrices for bioactive molecule detection. This book reviews the emerging trends in electrochemical sensors based on carbon composite materials & their applications. Carbon composite materials-based sensors offer elevated sensitivity, selectivity, stability and accuracy compared to other techniques, as well as improved portability through miniaturization. The developed sensors can be applied for routine applications in clinical and industrial settings, as well as in fundamental scientific research as they offer information regarding the mechanism and kinetics of electron transfer reactions occurring at the fabricated electrode surface.
