  • Patent number: 8716029
    Abstract: A biosensor that utilizes carbon nanotubes functionalized with a protein sequence. One domain of the multifunctional peptide sequence noncovalently binds to the surface of single-walled carbon nanotubes (SWNTs), while a second domain of the sequence recognizes and binds to a target molecule. The sequence of the peptide may be tailored to allow it to recognize and bind to specific target molecules, such as chemicals, biological materials, and explosives. The binding of the target molecule to the peptide may alter a material property of the SWNTs.

  • Patent number: 8273319
    Abstract: An improved method for enriched chirality of single wall carbon nanotubes is described. Genomic DNA, particularly salmon DNA (SaDNA) is shown to sort out single wall carbon nanotubes of specific chirality by a process of solubilization (dissolving in solution) and separation (such as centrifuging), without requiring more complex processes such as anion exchange chromatography. A possible reason for enhanced chirality separation using DNA may be attributed to its lowered GC (guanine-cytosine) content.

  • Patent number: 8137597
    Abstract: A one-part, pressure activated chemiluminescent material is disclosed. The free-flowing powder is made by coating microcapsules, filled with a solvent and dye, with a powdered oxalate and a solid source for hydrogen peroxide. The reaction begins when the capsules are crushed, releasing the solvent, which dissolves the oxalate and the source for hydrogen peroxide. The resulting reaction transfers energy to the dye, which produces light.
