Advanced Silk Protein Fragment Generation and Biomaterial Fabrication

This inventive concept envisions a next-generation system for generating silk protein fragments with tunable molecular weights and fabricating biomaterials with programmable properties, enabling the creation of advanced silk-based medical devices, wound dressings, and implants.

The original patent disclosed stable silk protein fragment compositions, but the current inventive concept addresses the limitations of those compositions by introducing a system that can generate silk protein fragments with tailored molecular weights and polydispersity, enabling the creation of advanced biomaterials with specific properties.

The new inventive concept comprises a system with multiple modules, including a processing module, a control module, a computer-aided design module, and a fabrication module. The processing module receives raw silk material and outputs silk protein fragments with predetermined polydispersity and molecular weight ranges. The control module adjusts processing parameters to achieve desired fragment characteristics. The computer-aided design module designs silk protein fragment structures with desired properties, and the fabrication module assembles the fragments into a biomaterial with the desired properties. This system enables the generation of silk-based nanofibers, implantable devices, and wound dressings with tailored properties.

The new claims introduce a paradigm shift in silk protein fragment generation and biomaterial fabrication by enabling the creation of programmable biomaterials with specific properties. This is a significant departure from the original patent, which focused on stable silk protein fragment compositions. The inventive concept's ability to generate silk protein fragments with tunable molecular weights and fabricate biomaterials with programmable properties is new and non-obvious.

Alternative embodiments of the inventive concept could include the use of different processing techniques, such as enzymatic digestion or chemical modification, to generate silk protein fragments with tailored properties. Additionally, the system could be adapted for use with other biomaterials, such as collagen or chitin, to create a range of programmable biomaterials.

The inventive concept has significant commercial potential in the medical device and biomaterials industries, with potential applications in wound healing, tissue engineering, and implantable devices. The ability to create programmable biomaterials with specific properties could revolutionize the field of biomaterials and enable the creation of new medical devices and treatments.
