Smart Sonoafterglow Nanobombs for High‐Contrast Imaging and Synergistic Gas‐Sonodynamic Therapy of Hypoxic Tumors

-sensitive imaging, robust tumor suppression, and potent induction of immunogenic cell death in vivo. Overall, unlike prior approaches that address either tumor imaging or hypoxia modulation alone, this work establishes a versatile sonoafterglow nanobomb for oxygen-independent, image-guided, and synergistic tumor theranostics.
