pH-responsive Zn2+-coordinated gellan gum/γ-polyglutamic acid hydrogel microspheres as functional biomaterials for intra-articular delivery: physicochemical design, smart release, and chondroprotective performance in osteoarthritis
Osteoarthritis (OA) is a degenerative joint disease characterized by progressive degradation of the articular cartilage matrix, pain-related functional impairment, and a paucity of effective disease-modifying therapies. Curculigoside (Cur), a bioactive compound isolated from Curculigo orchioides, possesses anti-inf...
