Northwestern University, USA, scientists have developed a method for sorting single-walled carbon nanotubes (SWNTs) that overcomes the problem of structural differences in the materials. The method works by exploiting subtle differences in the bouyant densities of carbon nanotubes as a function of their size and electronic behavior. The group found out that the SWNTs can be sorted by diameter and electronic structure.
