Surface functionalization of styrenic block copolymer elastomeric biomaterials with hyaluronic acid via a “grafting to” strategy

- Biocompatibility was imparted to SBC with HA via a “grafting to” strategy.
- The HA-modified samples presented a low adhesiveness to fibroblast.
- The HA modification stimulated the growth of fibroblast on the substrates.
- Fibroblast growth exhibited a strong dependence on HA molecular weight.
