Hypoxia and immunosuppression contribute to tumor resistance to radiotherapy (RT). Here the authors design a nanoprobe based on NIR-IIb emitting quantum dots for image-guided RT and modified with catalase to relieve hypoxia in the tumor microenvironment, enhancing the precision and efficacy of RT and promoting anti-tumor immune responses.
