Regio-isomerization boosts NIR-II photothermal conversion and multimodal imaging in conjugated polymer nanoparticles for effective cancer therapy.
Second near-infrared (NIR-II) photoacoustic imaging (PAI) and fluorescence imaging (FLI) have emerged as powerful tools for deep-tissue visualization, yet most organic probes remain limited to single imaging modality and lack therapeutic functions. Here, we report a regio-isomerization strategy to construct NIR-II-abso...
