Process for the production of silk fibroin hydrogels comprising the following steps: a) Obtaining the raw silk filament for example from cocoons, silk fabric, raw silk waste; b) Removing where present the sericin layer covering the silk fibroin fibers; c) obtaining a solution of fibroin in water; d) Treating the fibroin solution with water soluble polymers and/or with acid solutions with a pH lower than 4 and/or polar solvents and/or with crosslinking compounds. e) Washing the resulting material from said step b and so obtaining a silk fibroin hydrogel. |
