  • Mercapto-modified biocompatible macromolecule derivatives with low degree of mercapto-modification and the cross-linked materials and uses thereof
    Patent number: 10064889
    Abstract: The present invention discloses a mercapto-modified biocompatible macromolecule derivative with a low degree of modification. The mercapto-modified biocompatible macromolecule derivative not only maintains the initial structure, physiological function and biocompatibility as much as possible, but also allows the preparation of the biocompatible macromolecule cross-linked material with a low degree of cross-linking through the effectively chemical cross-linking with the introduced mercapto group. The present invention further discloses a disulfide-bond cross-linked biocompatible macromolecule material with a very low degree of cross-linking.
    Type: Grant
    Filed: March 23, 2016
    Date of Patent: September 4, 2018
    Assignee: Bioregen Biomedical (Changzhou) Co., Ltd.
    Inventors: Xiaozheng Shu, Weiping Zhong, Yunyun Wang, Meixia Yu
