NIR‐II Responsive Multifunctional Scaffold Enabling “Kill‐Modulation‐Build” Synergistic Therapy for Infectious Bone Defects

Advanced Science, EarlyView.
A novel multifunctional scaffold with photothermal effects is developed for infected bone defect repair. It facilitates angiogenesis and osteogenesis while eliminating bacteria through hyperthermia. Additionally, the scaffold promotes macrophage polarization from M1 to M2 via ROS scavenging, enhancing anti‐inflammatory activity. This study demonstrates
