Spectroscopic and Microscopic Characterizations of Functionalized Carbon Nanostructures

To create unique nanoscopic structures with real-world applications in the field of materials science, it is fundamentally necessary to comprehend and regulate the biochemical activity of functionalized carbon nanostructures. We report an extensive microscopic and spectroscopic characterization of chemically altered carbon nanotubes in this chapter. Electron microscopic techniques have gained enormous attention for analyzing structural morphologies of functionalized carbon nanostructures owing to its high precision electronic laser beam technology as compared to optical microscopy. Apart from the surface morphology, there are various biological activities governed by the presence of functional groups on the nanostructures. We have briefly reviewed a few spectroscopic techniques for qualitative and quantitative structural behavior of functionalized carbon nanostructures. Therefore, we discuss different characterization techniques for functionalized carbon nanostructures and deliberately list out the subsequent use of these nanostructures for their applications in the field of biomedicine and healthcare.
