Due to the spread of drug-resistant bacteria in hospitals, the development of antibacterial dressings has become a strategy to control
wound infections caused by bacteria. Here, we reported a green strategy for in situ biomimetic syntheses of
silver nanoparticles@organic frameworks/
graphene oxide (Ag@MOF-GO) in
sericin/
chitosan/
polyvinyl alcohol hydrogel. Ag@MOF-GO was synthesized in situ from the redox properties of
tyrosine residues in
silk sericin without additional chemicals, similar to a biomineralization process. The
sericin/
chitosan/Ag@MOF-GO dressing possessed a high porosity, good water retention, and a swelling ratio. The
hemolysis rate of the composite was 3.9% and the cell viability rate was 131.2%, which indicated the
hydrogel possessed good biocompatibility. The composite also showed excellent lasting antibacterial properties against drug-sensitive and drug-resistant pathogenic bacteria. The composite possessed excellent
hemostatic activity. The coagulation effect of the composite may be related to its effect on the red blood cells and platelets, but it has nothing to do with the activation of
coagulation factors. An in vitro cell migration assay confirmed and an in vivo evaluation of mice indicated that the composite could accelerate wound healing and re-epithelialization. In summary, the composite material is an ideal dressing for accelerating hemostasis, preventing
bacterial infection, and promoting wound healing.
