Electrospinning is presented as a technique for the debundling and isolation of carbon nanotubes. Nanotubes are electrospun with polyvinyl alcohol to produce composite nanofibers. Using a Raman spectroscopic technique, with a number of lasers of different excitation energies, the nanotubes are brought into resonance. Individual tubes (see image) can be identified from the presence of characteristic radial‐breathing modes.
