  • Crosslinking of biopolymers in a semi-solid state
    Patent number: 11248094
    Abstract: The present invention relates to methods of providing biocompatible/biodegradable hydrogels obtained by crosslinking of biopolymers (for example polysaccharides or proteins) in the semi-solid (modelling-clay like) state at water content below 70% by weight. The resulting materials can be applied in medicine, pharmacy and/or in cosmetics.
    Type: Grant
    Filed: October 9, 2018
    Date of Patent: February 15, 2022
    Assignee: SOLYPLUS GMBH
    Inventors: Richard Dolph Andersen, Annette Assogba-Zandt, Elena Maltseva, Andreas Voigt
