  • Patent number: 8597492
    Abstract: A method and system for detecting a DNA strand using carbon nanotubes or nanowires. A specific single strand of template DNA serves as a probe for its complementary strand in a solution containing DNA segments to be tested. The single-stranded sequence-specific DNA probe segment, whose ends are modified with amine, is attached between two carbon nanotubes/nanowires. When complementary strands representing DNA segments under test are brought near the probe strands, a dielectrophoresis (DEP) field may enhance the probability of selective hybridization between the complimentary target DNA and probe DNA. A change in electrical conductance in the probe strand occurs upon hybridization of the complementary target DNA with the single probe strand. This conductance change may be measured using the two carbon nanotubes or nano-dimensional electrodes. By exploiting nano-dimensional electrodes and single strand probe DNA, the proposed system is capable of accurately detecting a single molecule of DNA.

  • Publication number: 20130034610
    Abstract: Methods and materials for delivering biologically active molecules to cells in vitro or in vivo are provided. The methods and materials use carbon nanotubes or other hydrophobic particles, tubes and wires, functionalized with a linking group that is covalently bound to the nanotubes, or, alternatively, to the biologically active molecule, such as a protein. The biologically active molecule is preferably released from the nanotube when the complex has been taken up in an endosome.

  • Publication number: 20130030217
    Abstract: Disclosed is a novel method for the selective molecular conversion of raw material carbon nanotubes containing a mixture of metallic carbon nanotubes and semiconductive carbon nanotubes in a manner that is based on the electrical properties or diameter of the carbon nanotubes. The present invention causes a photoreaction of raw material carbon nanotubes containing a mixture of metallic carbon nanotubes and semiconductive carbon nanotubes with a disulfide or a sulfide of the following formula (I) or (II) (wherein R1 and R2 each independently represent a hydrocarbon group that may have a substituent) in an organic solvent that contains the raw material carbon nanotubes and the disulfide of the formula (I) or the sulfide of the formula (II), so as to selectively functionalize the metallic carbon nanotubes, or functionalize the carbon nanotubes diameter selectively.
