Abstract: Provided herein relates to methods and compositions for preparing a silk microsphere and the resulting silk microsphere. In some embodiments, the methods and compositions described herein are all aqueous, which can be used for encapsulating an active agent in a silk microsphere, while maintaining activity of the active agent during processing. In some embodiments, the resulting silk microsphere can be used for sustained delivery of an active agent encapsulated therein.

Abstract: The invention provides solid, self-emulsifying compositions for oral administration.

Abstract: The present invention is directed to the administration of a cannabinoid aerosol formulation using a soft mist inhaler (SMI) with reduced cannabinoid-related irritation and/or coughing. Described is an aerosol formulation comprising a cannabinoid in an ethanol solution and further comprising saccharin or a salt thereof, an aerosol formulation comprising a cannabinoid in a solution comprising ethanol and saline, and methods for the use thereof.

Abstract: The invention provides for compositions comprising one or more or at least two active ingredient(s), e.g., a cannabinoid, cannabinoid extract, terpene, or terpene extract. The invention includes cannabinoid formulations, including self-emulsifying formulations and micellar dispersions, as well as methods of making and using the same. Some formulations comprise a cannabinoid and surfactant. The formulations have improved dissolution, stability, absorption and/or oral bioavailability. Some of the formulations are rapid dispersing formulations.

Abstract: The invention is directed to a nanoprecipitate comprising a cannabinoid or a terpene, or combination thereof, a process of preparing the nanoprecipitate, and oral formulations comprising the nanoprecipitate, including beverage additives and edibles.

Abstract: The present invention provided for a novel process of forming silk fibroin gels, and controlling the rate of ?-sheet formation and resulting hydrogelation kinetics, by vortex treatment of silk fibroin solution. In addition, the vortex treatment of the present invention provides a silk fibroin gel that may be reversibly shear-thinned, enabling the use of these approach for precise control of silk self-assembly, both spatially and temporally. Active agents, including biological materials, viable cells or therapeutic agents, can be encapsulated in the hydrogels formed from the processes, and be used as delivery vehicles. Hence, the present invention provide for methods for silk fibroin gelation that are useful for biotechnological applications such as encapsulation and delivery of active agents, cells, and bioactive molecules.

Abstract: The invention relates to methods and compositions for preparing silk-based piezoelectric materials and methods for increasing piezoelectricity in silk matrices.

Abstract: This invention provides for compositions, methods and devices for rapidly converting silk fibroin solution into a silk fibroin gel using direct application of voltage, in a process called electrogelation. The silk fibroin gel may be reversibly converted back to liquid form by applying reverse voltage or may be converted further to ?-sheet structure by applying shear force or other treatments. The electrogelated silk may be used as an extracted bulk gel, spray or stream of gel for processing into materials or devices, or may be used as silk gel coating to devices. Active agents may be embedded in the silk gel for various medical applications. This invention also provides for methods and compositions for preparing adhesive silk pH-gels. For example, the method comprises reducing pH level of a silk fibroin solution to increase the bulk or local proton concentration of the silk fibroin solution, thereby forming adhesive silk gels.

Abstract: Embodiments of various aspects described herein are directed to silk-based compositions for ocular delivery of at least one active agent, e.g., at least one therapeutic agent and methods of using the same. In some embodiments, the silk-based compositions can provide sustained release of at least one therapeutic agent to at least a portion of an eye. Thus, some embodiments of the silk-based compositions can be used for treatment of an ocular condition, e.g., age-related macular degeneration.

Abstract: The present invention is directed to silk-based drug delivery compositions for controlled, sustained delivery of therapeutic agent(s) as well as methods of making and using the same.
