  • 摘要:
    Antimicrobial nanomaterials hold great promise for bacteria-infected wound healing. However, it remains a challenge to balance antimicrobial efficacy and biocompatibility for these artificial antimicrobials. Here we employed biocompatible genetic molecule DNA as a building material to fabricate antimicrobial materials, including self-assembled Y-shaped DNA-silver nanocluster composite (Y-Ag) and Y-Ag hydrogel (Y-Ag -gel). We demonstrate that macroscopic and microcosmic DNA-Ag composites can effectively inhibit bacterial growth but do not affect cell proliferation in vitro. In particular, Y-Ag spray can speed up the process of wound healing in vivo. Considering the efficacy and advantages of DNA -based materials, our findings provide a promising route to fabricate a novel wound dressing such as spray and hydrogel for therapeutic wound healing.
