Elaborated Bio‐Heterojunction With Robust Sterilization Effect for Infected Tissue Regeneration via Activating Competent Cell‐Like Antibacterial Tactic

Phototherapy, such as photothermal therapy (PTT) and photodynamic therapy (PDT) has been a powerful strategy to combat bacterial infection. However, the compact cell membranes of pathogenic bacteria, especially drug-resistant bacteria, significantly diminish the efficiency of heat conduction and impede the entrance of reactive oxygen species (ROS) into cells, resulting in unsatisfactory sterilization. Enlightened by the membrane feature of competent bacteria, herein a MXene/CaO
