Our research group focus on the researches on constructing living bio-functions and interface based on the synergy of supramolecular non-covalent bonds and covalent bonds, and established a bio-inspired lubricating hydrogel material system-a supramolecular regulatory functional material with partial gel-sol transition ability was developed. This unique hydrogel system opens up a feasible way for the design and preparation on biomimetic cartilage periosteum and soft robots.
