Injectable Amine Functionalized Graphene and Chondroitin Sulfate Hydrogel with Potential for Cartilage Regeneration Damaged cartilage does not readily heal and often requires surgical intervention that only modestly improves outcomes. A synthetic material that could be injected and covalently crosslinked in situ to form a bioactive, mechanically robust scaffold that promotes stem cell chondrogenic differentiation holds promise for next-generation treatment of cartilage lesions.
