Three-Dimensional BODIPY-Iron(III) Compound with Promoted H2O2-Response for NIR-II Photoacoustic Imaging Guided Chemodynamic/Photothermal Therapy

3D boron dipyrromethene (BODIPY)-Fe(III) coordination polymer nanoparticles can extend absorption to 1300 nm for enhanced ligand-to-metal transfer. The nanoparticles show good cytotoxic hydroxyl radical (•OH) generation ability, high photothermal conversion, and outstanding NIR-II photoacoustic imaging, displaying synergistic chemodynamic/photothermal therapy.
