    摘要: A surgical implant is provided which includes a body and a coating in contact with at least a portion of the body, the body including metallic magnesium, the coating including a hydrogel having an adhesion peptide contained therein. The adhesion peptide may be derived from an extracellular matrix protein and may be covalently bonded to the hydrogel. A method of making a surgical implant includes providing a magnesium based degradable implant body; applying and adhering a functionalized reactive silane based adhesion promoting layer to the implant body; providing a hydrogel monomeric solution having extracellular matrix adhesion peptides incorporated therein; and contacting the hydrogel monomeric solution with the adhesion promoting layer such that the hydrogel polymerizes and bonds to the adhesion promoting layer and encapsulates at least a portion of the implant.
