Single-walled carbon nanotubes have considerable potential as building blocks in future nanoscale electronics. The tubes exist in two modifications, metallic and semiconducting, which might be used in a range of electronic applications. One of the grand challenges is to separate metallic from semiconducting tubes in substantial quantities. In this respect, this article gives a brief overview over the separation techniques in this new field of nanotube research.
