Abstract

Disclosed is an external wound dressing formed of a bioprotein scaffolding that may include a pressure-sensitive adhesive impregnated in the bioprotein scaffolding. A method of wound treatment can include adhering an external wound dressing formed of a bioprotein scaffolding to an external injury site. Another method can include applying an adhesive to the skin of a patient, placing an external wound dressing formed of a bioprotein scaffolding over an injury site on the skin of the patient, and applying a sealing adhesive on top of the bioprotein scaffolding. Yet another method can include applying an adhesive to the skin of a patient, placing an external wound dressing formed of a bioprotein scaffolding over an injury site on the skin of the patient that has not been stitched, and applying a sealing adhesive on top of the bioprotein scaffolding.
