  • Methods for separating carbon nanotubes
    Patent number: 8193430
    Abstract: Disclosed herein too is a method that includes dispersing nanotubes in media that comprises flavin moieties substituted with solubilizing side chains, and/or non-flavin containing molecular species; self-assembling the flavin moieties and other non-flavin containing molecular species in a pattern that is orderly wrapped around the nanotubes to form a composite; introducing desired amounts of an optional reagent that competes with self-assembly in order to disturb the wrapping around nanotubes with moderate order; and centrifuging the mass of the nanotubes and the composites to extract the composite from other nanotubes that are not in composite form.
