  • Patent number: 7211439
    Abstract: The invention relates to a nanoparticle film comprising a nanoparticle network formed of nanoparticles interlinked by linker molecules. The linker molecules have at least two linker units that can bind to the surface of the nanoparticles. By introducing selectivity-enhancing units in the linker molecule, the selectivity of the nanoparticle film towards target analytes can be enhanced. A fine-tuning of the selectivity can be achieved by including a fine-tuning unit in the vicinity of the selectivity-enhancing unit. The nanoparticle film can be used to produce chemical sensors which are selective and stable in their performance.

  • Publication number: 20060246482
    Abstract: The present invention is related to the linker molecules comprising one or more nucleic acid binding group and one or more nanoparticle binding group which are connected covalently by a spacer group. The problem underlying the present invention is to provide methods for the controlled and selective metallisation of nucleic acids, the production of nanowires which may be used, e. g., in the formation of electronic networks and circuits allowing a high density arrangement, and the components of devices that may be incorporated in such networks and circuits. This problem is solved by a linker molecule which comprises one or more nucleic acid binding group(s) and one or more nanoparticle binding group(s) which are connected covalently by a spacer group. Such linkers can be used for the manufacture of nucleic acid/linker conjugates, nanoparticle/linker conjugates, and nanoparticle/linker/nucleic acid composites and further nanowires, electronic networks, electronic circuits and junctions comprising said nanowires.
