  • Patent number: 7940357
    Abstract: A multi-viewing display device includes a display panel for displaying images; a back light for supplying the light to the display panel; and a viewing converting unit having a plurality of parallax barriers for reflecting the light from the back light and non-reflecting the light from the display panel to control the path of the light in accordance with a desired viewing direction. The viewing converting unit may include a substrate; at least one layer of a parallax barrier made of high reflective material to reflect the light on the substrate; and at least one layer of the parallax barrier made of low reflective material to block the light on the first parallax barriers.

  • Publication number: 20100282605
    Abstract: The present invention relates to a nanoparticle sensor which is capable to identify an existence/nonexistence, a concentration, a size distribution and a component of the nanoparticles using an electrode pair having a separated distance of a nano-gap, in which the nanoparticle sensor includes a unit element configured with a plurality of unit electrodes electrically operated independently from each other and detects the nanoparticles based on the number of the unit electrodes electrically changed due to the nanoparticles captured into the nano-gap. The nanoparticle sensor of the present invention can detect the component, the size, the size distribution and the concentration of the nanoparticles by single measurement, have high reliability and regeneration while reducing a detection time by statistical method via a plurality of electrode pairs having the nano-gap, and detect even very low concentration of nanoparticles.

  • Publication number: 20100098966
    Abstract: The present invention relates to a process of preparing a nanogap electrode and a nanogap device using the same, and a preparing process according to the present invention is characterized in that reduced metal is grown by reduction reaction from a metal ion in solution on the surface of a metal pattern with a predetermined shape. A method of preparing a nanogap electrode according to the present invention has an advantage that nanogap electrodes having a gap distance of 1-100 nm, which are difficult to prepare by a conventional method, can be easily prepared in a reproducible and uniform manner.

  • Publication number: 20090221086
    Abstract: The present invention relates to an apparatus and a method for detecting the presence of a particular organic, inorganic, metallic, natural or synthetic biomaterial and the concentration thereof. More particularly, the present invention relates to an apparatus and a method for detecting the identity, presence or absence, and concentration of a material to be detected, by which the metal ions of the detection solution are reduced to metals by a material to be detected and are deposited as metallic nanoparticles, resulting in the change of the shape, size or pattern of the metallic nanoparticles, and the change in light transmittance caused thereby is measured to detect the presence or absence of the material and the concentration thereof.

  • Patent number: 7557044
    Abstract: Disclosed herein is a method of fabricating nano-components using nanoplates, including the steps of: printing a grid on a substrate using photolithography and Electron Beam Lithography; spraying an aqueous solution dispersed with nanoplates onto the grid portion to position the nanoplates on the substrate; depositing a protective film of a predetermined thickness on the substrate and the nanoplates positioned on the substrate; ion-etching the nanoplates deposited with the protective film by using a Focused Ion Beam (FIB) or Electron Beam Lithography; and eliminating the protective film remaining on the substrate using a protective film remover after the ion-etching of the nanoplates, and a method of manufacturing nanomachines or nanostructures by transporting such nano-components using a nano probe and assembling with other nano-components.
