Abstract:Electrochemical sensors have the advantages of simplicity, short analysis time, low cost and high sensitivity, which have attracted more and more attention in environmental analysis and pharmaceutical analysis. Various nanomaterials and signal amplification strategies have been prepared for the construction of electrochemical sensors, such as gold nanoparticles, bimetallic nanoparticles, functional graphene, carbon nanotubes, graphene quantum dots and metal organic frameworks. Carbon-based materials have excellent properties, including rich pore structure, high specific surface area, adjustable surface functionality, good electrical conductivity, and easy chemical functionalization, showing a broad application prospect in the field of electrochemical sensing. In this paper, the properties, structure and synthesis of carbon based materials are described in detail. The application of carbon-based materials in electrochemical sensing is discussed to effectively improve the sensitivity. Finally, the challenges and future development of carbon-based materials are prospected.
