  • Carbon nanotube sensors
    Patent number: 7013708
    Abstract: Nanotubes and nanotube-based devices are implemented in a variety of applications. According to an example embodiment of the present invention, a nanotube is doped with an impurity atom and used to detect the presence of a particular molecular species as a function of the particular molecular species bonding to the impurity atom. In one implementation, the doped nanotube responds electrically to the bonding of the particular molecular species to the impurity atom. With this approach, nanotubes such as single-walled carbon nanotubes can be doped to respond selectively to one or more types of molecular species.

  • Method for cutting nanotubes
    Patent number: 7008604
    Abstract: This invention relates generally to cutting single-wall carbon nanotubes (SWNT). In one embodiment, the present invention provides for preparation of homogeneous populations of short carbon nanotube molecules by cutting and annealing (reclosing) the nanotube pieces followed by fractionation.

In one embodiment, oxidative etching with concentrated nitric acid is employed to cut SWNTs into shorter lengths. The annealed nanotubes may be disbursed in an aqueous detergent solution or an organic solvent for the fractionation. Closed tubes can also be derivatized to facilitate fractionation, for example, by adding solubilizing moieties to the end caps.
