Wound healing in patients with diabetes is challenging because of chronic inflammation, inadequate vascularization, and susceptibility to infection. Current wound dressings often target specific stages lack comprehensive therapeutic approaches. This study introduces a novel approach using photodetachable sponge scaffold incorporating carbon nanotubes (CNTs), known for their high photothermal conversion efficiency, electrical conductivity, water absorption properties. The incorporated pyrrolidonecarboxylic acid zinc (PC1Z2), compound anti-inflammatory moisturizing properties, which was cross-linked within network CNTs decellularized dermal matrix. resulting shape-memory actively interfaces endogenous electric fields, facilitating signal transmission skin cells accelerating tissue repair. Upon exposure near-infrared (NIR) light, the PC1Z2 enhanced antibacterial efficacy (98 %) through conversion, promoting metabolism at site. Notably, absorbed exudates gradually released Zn2+, effectively reducing inflammation mice. In diabetic rat model, exudates, reduced accelerated granulation formation, angiogenesis, re-epithelialization. innovative dressing shows promise enhancing wounds.
