This invention provides for a process of rapidly forming silk fibroin gelation through ultrasonication. Under the appropriate conditions, gelation can be controlled to occur within two hours after the ultrasonication treatment. Biological materials, including viable cells, or therapeutic agents can be encapsulated in the hydrogels formed from the process and be used as delivery vehicles.
