Raman spectroscopy proved to be an extremely useful technique for characterization of novel carbon materials. Further progress in understanding the chemical and structural transformations in complex carbon-based systems requires ability to obtain Raman spectra with nanometer-scale resolution. Tip Enhanced Raman Scattering ( TERS) can address such a demand. Thanks to the recent advances in instrumentation, TERS imaging has become fast and user friendly to be used for everyday measurements. We report consistent chemically specific nanoscale Raman imaging of fullerens, carbon nanotubes and graphene in both the single-component samples and the complex samples comprized of up to 4 individual components. Structural features of 1-D and 2-D materials, both naturally occurring and artificially created can be routinely probed by Raman spectroscopy with spatial resolution below 5 nm in case of 1-D materials and about 10-15 nm for 2D materials.
