Daejong YANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11125620
    Abstract: A substrate for sensing, a method of manufacturing the substrate, and an analyzing apparatus including the substrate are provided. The substrate for sensing includes: a support layer; a plurality of metal nanoparticle clusters arranged on the support layer; and a plurality of perforations arranged among the plurality of metal nanoparticle clusters. The plurality of metal nanoparticle clusters each comprise a plurality of metal nanoparticles stacked in a three-dimensional structure. Each of the plurality of perforations transmits incident light therethrough.
    Type: Grant
    Filed: May 25, 2018
    Date of Patent: September 21, 2021
    Assignees: SAMSUNG ELECTRONICS CO., LTD., CALIFORNIA INSTITUTE OF TECHNOLOGY
    Inventors: Daejong Yang, Hyunjun Cho, Youngzoon Yoon, Hyuck Choo
  • Patent number: 10859499
    Abstract: An apparatus and method for quantitatively sensing and analyzing a concentration of biomolecules using Raman peak shift are disclosed. The quantitative molecular sensing apparatus includes an illumination optical system including a light source configured to irradiate excitation light onto an object, a detection optical system including an optical detector configured to detect light scattered from the object, and a signal processor configured to analyze properties of the object based on signal output by the detection optical system and to calculate a concentration of target molecules in the object based on a Raman peak shift value over a predetermined time period.
