We report fast chemically specific imaging of individual single wall carbon nanotubes ( SWCNT) and graphene oxide ( GO) co-deposited on gold using Tip Enhanced Raman Scattering (TERS). Spatial resolution of 10-20 nm can be routinely achieved in our setup at speeds comparable with the speed of high quality AFM imaging. We demonstrate not only the capability to unambiguously segregate graphene oxide from SWCNTs, but also detect non-uniformity of the properties of the carbon nanotubes based on their TERS spectra.
