  • Patent number: 11648208
    Abstract: Provided are a nanocomposite including a nano-drug delivery system; and a ginseng extract or a ginsenoside isolated therefrom, and a preparation method thereof, in which the nanocomposite may be used for the prevention or treatment of cancer and inflammatory diseases. The metal nanocomposite of the present invention may be prepared in a uniform size without using an additional reducing agent or stabilizing agent in a significantly shortened time, as compared with known metal nanoparticles. Further, since the metal nanocomposite has high solubility in water and high targeting ability for cancer cells, it can be advantageously developed as drugs. Further, the metal nanocomposite exhibits high anti-cancer and anti-inflammatory activities, and thus may be usefully applied to prevention or treatment of cancer and inflammatory diseases.
    Type: Grant
    Filed: January 6, 2021
    Date of Patent: May 16, 2023
    Assignee: UNIVERSITY-INDUSTRY COOPERATION GROUP OF KYUNG HEE UNIVERSITY

  • Publication number: 20090032873
    Abstract: Methods and apparatus for producing a semiconductor on glass (SiOG) structure include: subjecting an implantation surface of a donor single crystal semiconductor wafer to an ion implantation process to create an exfoliation layer of the donor semiconductor wafer; bonding the implantation surface of the exfoliation layer to a glass substrate using electrolysis; separating the exfoliation layer from the donor semiconductor wafer, thereby exposing a cleaved surface of the exfoliation layer; subjecting the cleaved surface of the exfoliation layer to a dry etching process to produce a single crystal semiconductor layer of about 5-20 nm thickness; and forming a thin film transistor in the thin semiconductor layer.
