> The new biomaterial comprises two components: a bioactive peptide that binds to transforming growth factor beta-1 (TGFb-1) — an essential protein for cartilage growth and maintenance — and modified hyaluronic acid, a natural polysaccharide present in cartilage and the lubricating synovial fluid in joints.
and application:
