  • Publication number: 20110112287
    Abstract: A method for covalently binding target molecules to carbon nanoparticles via at least one bridge molecule includes converting carbon nanoparticles to acyl carbon nanoparticles using a carbonyl compound of the at least one bridge molecule in the presence of a Lewis acid under Friedel-Crafts conditionsm, where the acyl carbon nanoparticles include a nucleofuge in the omega position. The target molecule is covalently bound to the acyl carbon nanoparticles via nucleophilic substitution of the nucleofuge in the omega position.

  • Patent number: 7161107
    Abstract: A method for separating metallic carbon nanotubes and semi-conducting carbon nanotubes includes providing a suspension containing a plurality of individual metallic carbon nanotubes and semi-conducting carbon nanotubes in a liquid, for which the dielectric constant ?L meets the requirement: ?M>?L>?H, wherein ?M is the dieletric constant of the metallic carbon nanotubes and ?H is the dielectric constant of the semi-conducting carbon nanotubes. A a non-homogeneous electric alternating field is applied to the suspension to create spatially separate species of the metallic carbon nanotubes and the semi-conducting carbon nanotubes. At least one of the separate species is then removed.
