Patent number: 10548981Abstract: The present invention provides for novel sustained release silk-based delivery systems. The invention further provides methods for producing such formulations. In general, a silk fibroin solution is combined with a therapeutic agent to form a silk fibroin article. The article is then treated in such a way as to alter its conformation. The change in conformation increases its crystallinity or liquid crystallinity, thus controlling the release of a therapeutic agent from the formulation. This can be accomplished as single material carriers or in a layer-by-layer fashion to load different therapeutic agents or different concentrations of these agents in each layer.Type: GrantFiled: December 3, 2013Date of Patent: February 4, 2020Assignees: EIDGENOSSISCHES TECHNISCHE HOCHSCHULE (THE SWISS FEDERAL INSTITUTE OF TECHNOLOGY), TRUSTEES OF TUFTS COLLEGEInventors: David L.
