Abstract Intractable infected microenvironments caused by drug‐resistant bacteria stalls the normal course of wound healing. Sono‐piezodynamic therapy (SPT) is harnessed to combat pathogenic bacteria, but superabundant reactive oxygen species (ROS) generated during SPT inevitably provoke severe inflammatory response, hindering tissue regeneration. Consequently, an intelligent nanocatalytic membrane composed poly(lactic‐co‐glycolic acid) (PLGA) and black phosphorus /V 2 C MXene bio‐heterojunctions (2D ‐bioHJs) devised. Under ultrasonication, 2D ‐bioHJs effectively eliminate disrupting metabolism electron transport chain (ETC). When ultrasonication ceases, they enable elimination SPT‐generated ROS. The act as a “lever” that achieves balance between ROS generation annihilation, delivering both antibacterial anti‐inflammatory properties engineered membrane. More importantly, in vivo assays corroborate membranes transform stalled chronic environment into regenerative one eradicating bacterial population, dampening NF‐κB pathway promoting angiogenesis. As envisaged, this work demonstrates novel tactic arm with programmed effects remedy refractory wounds from drug‐fast bacteria.
