NIR-Light-Activable Macrophage Polarization Orchestration Using Laser-Structured Janus Nanoplatform Derived from Waste for Infected Wound Healing.
A stimuli-responsive wound dressing that integrates carboxylated eggshell membrane with electrosprayed tannic acid/iron particles trapped between electrospun Poly-L-lactide-caprolactone (PLCL) layers and precisely laser-structured to increase porosity and fit the wound size offers an antibiotic-free strategy that disinfects, modulates inflammation, and promotes regeneration of infected wounds.
