Overview of material design for the fabrication of soft and stiff fibrous networks. (a) Hydroxyl groups on hyaluronic acid (HA) were modified with methacrylates to form MeHA at various modification levels (soft: ~30%, stiff: ~97%). (b) Michael type addition reactions were used to conjugate RGD (yellow) and FITC (green) peptides on MeHA. Representative maximum projection images of suspended and hydrated electrospun fibers and schematic showing fiber composition for (c) soft and (d) stiff fibrous networks. Scale bar is 20 μm. Dashed lines indicate kinetic chains generated by methacrylate radical polymerization.
