Schematic diagram showing various paths to fabricate elastin-based hydrogels. The single/blended polymer solution is poured into a mold, and a) freeze-dried, b) chemically or physically cross-linked to form a hydrogel. C) The polymer solution was mixed with salt and poured in a mold to cast. The disc was placed in in a high pressure vessel for gas foaming by dense gas, then placed in water to leach out the salt, so forming a porous scaffold.
