Large-scale single-chirality separation of single-wall carbon nanotubes by simple gel chromatography

Nature Communications, 2011
Monostructured single-wall carbon nanotubes (SWCNTs) are important in both scientific research and electronic and biomedical applications; however, the bulk separation of SWCNTs into populations of single-chirality nanotubes remains challenging.
