Tunable Silk Protein Fragment Compositions for Advanced Materials and Therapies

This inventive concept envisions a next-generation silk protein fragment technology, allowing for the creation of bespoke materials with tunable molecular weights, polydispersity, and mechanical properties. This paradigm shift enables the development of advanced materials and therapies with unprecedented biocompatibility, strength, and versatility.

The original patent disclosed stable silk protein fragment compositions, but these were limited by their fixed molecular weights and properties. The new inventive concept addresses these limitations by introducing a system for producing silk protein fragment compositions with tunable molecular weights and polydispersity, thereby expanding the potential applications of silk-based materials.

The new inventive concept comprises a processing module that adjusts fragmentation conditions to achieve a desired average molecular weight and polydispersity, and a quality control module that ensures the removal of sericin and process contaminants to levels acceptable in pharmaceutical, medical, and consumer cosmetic markets. This allows for the creation of silk protein fragment-based materials with programmable mechanical properties, suitable for a wide range of applications. The inventive concept also encompasses silk protein fragment-based composite materials, bioink compositions, and delivery systems for therapeutic agents, all of which benefit from the tunable properties of the silk protein fragments.

The new claims introduce a fundamental shift in the production and application of silk protein fragments, moving from fixed molecular weights and properties to tunable and programmable characteristics. This inventive step enables the creation of advanced materials and therapies that were previously unachievable with the original patent's technology.

Alternative embodiments of the inventive concept could include the use of different silk protein fragment sources, such as recombinant silk proteins or genetically engineered silkworms. Variations of the processing module could also be explored, including the use of different fragmentation techniques or the incorporation of additional processing steps to further tailor the silk protein fragment compositions.

The tunable silk protein fragment technology has far-reaching commercial potential in industries such as pharmaceuticals, medical devices, consumer cosmetics, and advanced materials. The ability to create bespoke materials with tailored properties will enable the development of new products and therapies with unprecedented performance, safety, and efficacy.
