A Smart Near‐Infrared Carbon Dot‐Metal Organic Framework Assemblies for Tumor Microenvironment‐Activated Cancer Imaging and Chemodynamic‐Photothermal Combined Therapy

in the TME to form highly reactive hydroxyl radicals (•OH) by Fenton reaction, which achieves the chemodynamic therapy of tumors. Thus, efficient synergistic chemodynamic-photothermal dual mode therapy is achieved under fluorescence imaging guidance with TME response.
