Oxygen-replenished synergistic phototherapy via catalase, and metallic nanocatalysts with/- the co-loading of PS. (A) Schematic illustration of the preparation process of the Au@mSiO₂/Ce6@Catalase@DSPE-PEG-RGD probe and the tumor-targeted imaging and therapy. Adapted with the open access figure from ref. [41]. (B) Schematic illustration of preparing Pd@Pt-PEG-Ce6. Adapted with permission from ref. [42]. (C) Schematic illustration of the ICG-PtMGs@HGd nanocarriers as H₂O₂-driven oxygenator for multimodal imaging-guided enhanced synergistic PDT and PTT treatments in solid tumors. Adapted with permission from ref. [45]. (D) Schematic illustration of the photo-enhanced tumor via the PB@SiO₂-PEG nanocatalysts loaded with ZnPc (PSPZP NCs). Adapted with permission from ref. [46]. (E) Schematic illustration of AHBIP nanoplatform for CT/PA imaging-guided dually-enhanced phototherapy of tumors. Adapted with permission from ref. [50].
