  • Publication number: 20110198542
    Abstract: An electrically conductive carbon nanotube-metal composite ink may include a carbon nanotube-metal composite in which metal nanoparticles are bound to a surface of a carbon nanotube by chemical self-assembly. The electrically conductive carbon nanotube-metal composite ink may have higher electrical conductivity than a commonly used metal nanoparticles-based conductive ink, and may also be used in deformable electronic devices that are flexible and stretchable, as well as commonly used electronic devices, due to the bending and stretching properties of the carbon nanotube itself.

  • Publication number: 20110180968
    Abstract: A method for making a carbon nanotube metal composite includes the following steps. A number of carbon nanotubes is dispersed in a solvent to obtain a suspension. Metal powder is added into the suspension, and then the suspension agitated. The suspension containing the metal powder is allowed to stand for a while. The solvent is reduced to obtain a mixture of the number of carbon nanotubes and the metal powder.

  • Patent number: 7985869
    Abstract: As demonstrated herein, the ligand exchange chemistry of phosphine-stabilized Au11 clusters with ?-functionalized thiols is a powerful synthetic method that provides convenient access to a diverse family of functionalized Au11 clusters. The general nature of the presented ligand exchange approach, in combination with the ease preparation, makes this approach of broad utility. The approach is general and shows the high tolerance for a wide variety of functional groups. Mechanistic studies provided conclusive evidence that the Au11 core of the precursor particle remains intact during ligand exchange and showed that the ligand exchange of these particles follows a different pathway than for ligand exchanges of larger gold nanoparticles such as “Au101(PPh3)21Cl5”. Optical studies of the products show a strong dependence on the nature of the stabilizing thiol ligands.

  • Publication number: 20110111138
    Abstract: Metal complexes adapted to form conductive metal films and lines upon deposition and treatment. The metal complex can be a covalent complex and can comprise a first and second ligand. Low temperature treatment can be used to convert the complex to a metal. The metal films and lines can have low resistivity and work function similar to pure metal. Coinage metals can be used (e.g., Ag, Au, Cu). The ligands can be dative bonding ligands including amines, unsymmetrical amines, and carboxylate ligands. Sulfur complexes can be used. Carboxylate ligands can be used. The complexes can have a high concentration of metal and can be soluble in aromatic hydrocarbon solvent. The ligands can be adapted to volatilize well. Inkjet printing can be carried out. High yields of metal can be achieve with high conductivity.

  • Publication number: 20100284860
    Abstract: An article is provided for immobilizing functional organic biomolecules (e.g. proteins, DNA, and the like) through a covalent bond to a thiolate or disulfide monolayer to a metal surface wherein an extra activation step of the surface layer or an activation step of the functional biomolecules or bioreceptors could be avoided. The monolayer can contain, but is not limited to, two moieties. One has a group that resists nonspecific adsorption and another has a group that directly (without activation) reacts with functional groups on the biomolecules. In addition, poly(ethylene oxide) groups are incorporated in the monolayer surfaces to resist the nonspecific adsorption and to enhance the specific affinity interactions. A sensor device including these monolayers is also provided to perform reproducible, sensitive, specific and stable bioanalysis.
