College of Engineering, Bangalore, 560019, IN Journal Article 2021 07 13 Abstract Carbon nanomaterial has garnered interest in the research fraternity owing to the multiple advantages which includes its earth abundance, good electronic conductivity, excellent tolerance to acidic/alkaline media, and very good biocompatibility. Because of the above-mentioned advantages, they have found their way through applications in catalysis, sensing environmental remediation, and biological application. Heteroatom doping and organo-functionalization of carbon materials greatly extends the arsenal of these materials and their potential for a spectrum of application particularly in the field of electrochemical sensing. This review focusses on the creation and development in the design of electrochemical sensors based on the usage of doped and organo-functionalized carbon materials. Emphasis is given on the distinct properties and synergistic effects resulting from functionalization and doping. We hope that this review would throw light into the minds of researchers who would like to tune and turn their work, such that it promotes further activities in this particular field of research.
