  • Catalytic microgelators for decoupled control of gelation rate and rigidity of biological gels
    Patent number: 12201730
    Abstract: Provided herein are stimulus-responsive polymer microgelator particles that can activate fibrin fiber formation from their surfaces by actively ejecting thrombin to form an interconnected fibrin network with an increased elastic modulus and desirable microstructure. The use of the microgelators enables the decoupling of gelation rate and gel rigidity.
