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.
