  • Patent number: 8227582
    Abstract: The present invention provides an improved process for the direct and selective metallization of nucleic acids via metal nanoparticles produced in-situ in which a nucleic acid specific metal complex is reacted with a nucleic acid to produce a metal complex-nucleic acid conjugate, non-conjugated metal complex and/or non-conjugated by-products are removed, and the metal complex-nucleic acid conjugate is reacted with a reducing agent to produce a metal nanoparticle-nucleic acid composite. The metal nanoparticle-nucleic acid composites may be used, e. g., in the formation of nanowires, for electronic networks and circuits allowing a high density arrangement.

  • Patent number: 8173842
    Abstract: The invention relates to tuned multifunctional linker molecules for charge transport through organic-inorganic composite structures. The problem underlying the present invention is to provide multifunctional linker molecules for tuning the conductivity in nanoparticle-linker assemblies which can be used in the formation of electronic networks and circuits and thin films of nanoparticles. The problem is solved according to the invention by providing a multifunctional linker molecule of the general structure CON1—FUNC1—X—FUNC2—CON2 in which X is the central body of the molecule, FUNC1 and FUNC2 independently of each other are molecular groups introducing a dipole moment and/or capable of forming intermolecular and/or intramolecular hydrogen bonding networks, and CON1 and CON2 independently of each other are molecular groups binding to nanostructured units comprising metal and semiconductor materials.

  • Patent number: 8077476
    Abstract: An electronic device mounting structure includes a thermally conductive base, a busbar located on the base, an electronic device mounted on the busbar, a thermally conductive wall standing on the base and having first and second portions located opposite each other across the electronic device, and a plate spring supported by the first and second portions of the wall. The plate spring presses the electronic device against the base so that thermal resistance between the electronic device and the base is reduced. The plate spring has a thermal conductivity so that heat in the electronic device is transferred to the wall through the plate spring.
