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.Type: GrantFiled: May 22, 2006Date of Patent: July 26, 2011Assignee: State of Oregon Acting by and Through the State Board of Higher Education on Behalf of the University of OregonInventors: James E.

Publication number: 20110111138Abstract: 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.Type: ApplicationFiled: November 8, 2010Publication date: May 12, 2011Inventors: Richard D. McCullough, John A.

Publication number: 20100284860Abstract: 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.Type: ApplicationFiled: July 22, 2010Publication date: November 11, 2010Applicant: IMECInventors: Filip Frederix, Kristien Bonroy, Karolien Jans
