Abstract

The present disclosure discloses an implantable recombinant collagen microparticle and a preparation method therefor. At present, although materials used in the field of soft tissue filling, such as animal collagen and sodium hyaluronate, have good effects, the materials still have problems such as low biosafety, residual cross-linking agents, and a short maintenance time. In order to solve the above problems of existing medical aesthetic materials, the present disclosure prepares an implantable recombinant collagen microparticle by using a method of self-assembly combined with physical cross-linking. The microparticle becomes an injectable milky white opaque or colorless and transparent gel after being completely swollen with a water solvent. Compared with traditional medical aesthetic fillers, the gel prepared by the present disclosure has the characteristics of a good biocompatibility, a long degradation period, a simple preparation process, easy mass production, etc.
