Abstract: This disclosure relates to collagen-like polypeptides and materials containing the same and uses in biomedical applications. In certain embodiments, this disclosure contemplates that collagen-like polypeptides and materials containing the same are functionalized with proteins or small molecules to create useful scaffolds for drug delivery or testing. In certain embodiments, collagen-like polypeptides and materials containing the same are used in cardiac patches, cosmetic surgery, bone grafts, tissue regeneration, and wound healing.

Abstract: The thermodynamics of self-assembling peptides may be altered to produce different morphologies. By altering environmental factors, initiation and propagation of self-assembly processes may be altered, thereby consequently altering the morphology of the resultant structure.

Abstract: The present disclosure provides spun fibers of proteins useful for the fibers, fiber networks and nonwoven fabrics for medical use, with these materials characterized by good biocompatibility properties (e.g., low tendency toward thromboses and inflammation when implanted into a human or animal). These materials can be fabricated from gelatin, collagen or elastin-mimetic proteins, functionalized proteins of the foregoing types, crosslinked functionalized proteins of the foregoing types, and there may be incorporated nonproteinaceous polymers and/or therapeutic proteins or other medicinal compounds. Additionally, there may be living cells colonized on the material of the present invention or living cells may be incorporated during the fabrication process. These materials can be used in medical applications including, without limitation, vascular grafts, reinforcement of injured tissue, wound healing, artificial organs and tissues, prosthetic heart valves and prosthetic ureters.
