Heterogeneous‐Structure‐Based AuNBs@TiO2 Nano‐Photosensitizers for Computed Tomography Imaging Guided NIR‐II Photodynamic Therapy and Cancer Metastatic Prevention

Photodynamic therapy (PDT) is a minimally invasive cancer treatment that, despite its significant attention, faces limitations in penetration depth, which restrict its effectiveness. Herein, it is found that gold nanobipyramid (AuNBs) coated with TiO
