Method for preparing hyaluronic acid hydrogel fine particle and its application in repair of articular cartilage defect

摘要

Method for preparing hyaluronic acid hydrogel microparticle and its application in preparation of the drug which repairs articular cartilage defectMethod for preparing hyaluronic acid hydrogel fine particlesHyaluronic acid and anhydrous methacrylic acid.(b) the acrylic acid methylated hyaluronic acid copolymer and the photopolymerization initiator are mixed.Hyaluronic acid hydrogel is obtained by photopolymerization reaction with ultraviolet light.(c) through the screen of the hyaluronic acid hydrogel, the hyaluronic acid hydrogel fine particles are obtained.Diagram
