Persistent Regulation of Tumor Hypoxia Microenvironment via a Bioinspired Pt‐Based Oxygen Nanogenerator for Multimodal Imaging‐Guided Synergistic Phototherapy

Multifunctional nanoplatforms for imaging-guided synergistic antitumor treatment are highly desirable in biomedical applications. However, anticancer treatment is largely affected by the pre-existing hypoxic tumor microenvironment (TME), which not only causes the resistance of the tumors to photodynamic therapy (PDT), but also promotes tumorigenesis and tumor progression. Here, a continuous O
