An Overview of Carbon-Based Nanomaterials and Their Derivatives for Different Sensing Applications

Carbon based nanomaterials (CNM), henceforth mentioned as CNMs, are the classes of materials which consist of basic carbon entities as the prime architecture in the composition. Usually, CNMs comprise 2D graphene sheets, 1D carbon nanotubes, 0D carbon quantum dots, and 3D carbon nanoflowers. The alterations in the electronic configurations in the different nano-scaled systems invoke the different sensing applications and their responses, ranging from electrochemical, biosensing, amperometry, piezoelectric sensing, etc., elicited differentially from CNMs like Carbon nanotubes, Graphene sheets, Carbon dots, Carbon nanoflowers, etc., which would be highlighted with recent trend of work in this domain. Besides that, the real-life applications of CNMs in few agricultural applications would also be explained with past and recent trends with their discoveries. The underlying specific sensing properties at the atomic and electronic dimensions of different classes of CNMs would be unraveled in this chapter to showcase the significant sensing attributes existing in the inherent carbon-based nanomaterials and its modified parts for specific type of sensing applications.
