Hydrogels can be formed from reprocessed silkworm silk . These gels are formed with aqueous solutions of the fibroin prepared as outlined earlier. The rate of sol–gel transition is directly dependent on temperature (higher the temperature the more rapid the gelation), pH (lower the pH the more rapid the gelation), and solids content (higher the solids higher the rates of gelation).
