20140093580 | SILK-BASED DRUG DELIVERY SYSTEM - 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. | 04-03-2014 |

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 crytallinity 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. | 08-02-2012 |
