  • Graft polymer and composite material containing the same
    Patent number: 11629213
    Abstract: A graft polymer is provided, which includes a polymer backbone with a plurality of hydroxy groups, protection group modified histidine grafted onto the side of the polymer backbone, and hydrophilic polymer having terminal reactive group grafted onto the side of the polymer backbone. The graft polymer coating can be applied to metal material to form a composite material, which can be implanted into an organism to reduce adhesion problems.
    Type: Grant
    Filed: December 24, 2020
    Date of Patent: April 18, 2023
    Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE
    Inventors: Ting-Yu Shih, Chia-Chun Wang, Lu-Chih Wang, Yuan-Kun Yu, Shu-Fang Chiang, Yi-Ting Hsieh, Yu-Chun Liu, Jing-Wen Tang
  • Biomedical composition for skin care and/or maintenance and delaying and/or inhibiting skin aging and the use thereof
    Patent number: 11246822
    Abstract: A method for skin care and/or maintenance including applying or administering a preparation to a subject is provided. The preparation includes a biomedical composition, and the biomedical composition includes an effective amount of micelle, wherein the micelle includes a hyaluronic acid and/or a derivative thereof and a modified histidine. The modified histidine is grafted to at least one primary hydroxyl group of the hyaluronic acid and/or the derivative thereof, and a graft ratio of the modified histidine is 1-100%. Moreover, the hyaluronic acid and/or the derivative thereof and the modified histidine form the micelle on a weight percentage of 0.2-300:1.
