Length Fractionation of Carbon Nanotube Using Centrifugation



Jeffrey A. Fagan, Matthew Becker, Jae H. Chun, Erik K. Hobbie


A recent article by Arnold et al. (Nature Nanotech., 1, 60-65, 2006)1 demonstrated the use of ultracentrifugation on single wall carbon nanotubes (SWNTs) within a density gradient to produce chirality separation of the nanotubes. The authors of this letter wish to note that this technique can also be used to produce length fractionated SWNTs, by exploiting the transient motion of the SWNTs in response to the applied gravitational field.
