Wound treatments with crosslinked protein amorphous biomaterials
Biomaterials and the related methods of making and using biomaterials for wound treatment. The biomaterial defines an amorphous material that is crosslinked with one or more crosslinking agents an includes aggregated complexes having homogenously distributed biocoacervated components. The biocoacervated components include one or more soluble or solubilized primary proteins combined with one or more glycosaminoglycans and one or more biocompatible solvents. The biomaterial can be utilized by administering the biomaterial to a wound.
