Photo-Activated Cu-ZIF-8 Integrated Sprayable Hydrogels for Accelerated Wound Healing

, significantly promoted cell migration (66.7% at 24 h), and showed low cytotoxicity. In vivo, it accelerated wound healing (99.91% on day 10), reduced inflammation (increased tumor necrosis factor-α (TNF-α) expression), and enhanced angiogenesis (CD31 fluorescence up to 154.7). This rationally designed dressing combines targeted antibacterial action with regenerative capacity, presenting a promising strategy for treating infected wounds.
