Ultrasound‐Responsive Carbon Monoxide Microneedle for Enhanced Healing of Infected Diabetic Wounds

@CO not only effectively inhibited the S. aureus and MRSA infection but also promoted fibroblasts proliferation and migration under hyperglycemic physiology, thereby accelerating diabetic wound healing. Collectively, the approach effectively addresses the impaired skin regeneration function in diabetic wounds and offers a promising therapeutic strategy for the efficient healing of infected diabetic wounds.
