  • Patent number: 9040158
    Abstract: A generic route for synthesis of asymmetric nanostructures. This approach utilizes submicron magnetic particles (Fe3O4—SiO2) as recyclable solid substrates for the assembly of asymmetric nanostructures and purification of the final product. Importantly, an additional SiO2 layer is employed as a mediation layer to allow for selective modification of target nanoparticles. The partially patched nanoparticles are used as building blocks for different kinds of complex asymmetric nanostructures that cannot be fabricated by conventional approaches. The potential applications such as ultra-sensitive substrates for surface enhanced Raman scattering (SERS) have been included.

  • Publication number: 20150065694
    Abstract: Here, we describe a preassembled plasmonic resonance nanocluster. One embodiment is used for microbe detection and typing. The metallic nanoparticle acceptors with microbe surface antigen epitope, and quantum dot (QD) donors with Fab antibody, are assembled into an immuno-mediated 3D-oriented complex with enhanced energy transfer and fluorescence quenching. The coherent plasmonic resonance between the metal and QD nanoparticles is exploited to achieve improved donor-acceptor resonance within the nanocluster, which in the presence of microbial particles is disassembled in a highly specific manner. The nanocluster provides high detection specificity and sensitivity of the microbes, with a sensitivity limit down to 1-100 particles per microliter and to attomolar levels of a surface antigen epitope. A few specific examples of the plasmonic resonance nanocluster used in microbe detection are disclosed along with ways in which the complex can be easily modified for additional microbes.

  • Patent number: 8951634
    Abstract: The present invention relates to a filler material for a floor, comprising a natural base material and a mixture containing loess and a resin in powder or pellet form, as well as to a method for producing the filler material. The filler material of the present invention uses the natural base material and is thus environmentally-friendly and not harmful to the human body. Further, in the event rice husks are used as the natural base material, a person slipping on the floor is protected from burning caused by friction as the rice husks have a high moisture content. In addition, the loess contained in the filler material keeps the floor from becoming moldy and emits far infrared radiation, and therefore is beneficial to the human body. The resin emulsion of the filler material prevents the natural base material from generating dust, thus preventing dust from entering the human body via the respiratory organs of the human body.

  • Patent number: 8771661
    Abstract: This invention relates to high surface area materials, such as nanoparticles, that are coated with metal ions. These modified nanoparticles have active sites that bind various gases and/or odorous compounds, thereby removing these compounds from a medium such as air or water. Metal ions are adsorbed onto the surface of the nanoparticle and bound strongly to the surface. By selection of the metal ion, specific gaseous compounds and/or odorous compounds can be targeted and removed efficiently and effectively from both aqueous phase and from the air. The modified nanoparticles are useful in numerous article of manufacture for industrial and consumer use.

  • Publication number: 20140174906
    Abstract: A system and method employing sunlight energy for the reduction of carbon dioxide into methane and water are disclosed. Methane gas may then be stored for later use as fuel. The system and method may use inorganic capping agents that cap the surface of semiconductor nanocrystals to form photocatalytic capped colloidal nanocrystals, which may be deposited on a substrate and treated to form a photoactive material. The photoactive material may be employed in the system to harvest sunlight and produce energy necessary for carbon dioxide reduction. The system may also include elements necessary to collect and transfer methane, for subsequent transformation into electrical energy.

  • Patent number: 8759054
    Abstract: The present invention relates to DNA loaded gold nanoparticles embedded in sharp carbonaceous carriers useful for higher DNA delivery efficiently into plants. These nanogold embedded carbon matrices are prepared by heat treatment of biogenic intracellular gold nanoparticles. The DNA delivery efficiency is tested on model plants. These materials reveal good dispersion of the transport material, producing a greater number of GUS foci per unit area. The added advantages of the composite carrier are the lower plasmid and gold requirements. Plant cell damage with the prepared carbon supported particles is very minimal and can be gauged from the increased plant regeneration and transformation efficiency compared to that of the commercial micrometer sized gold particles. This can be attributed to the sharp edges that the carbon supports possess, which lead to better piercing capabilities with minimum damage.
