Rare Metals, EarlyView.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...
