Sonosensitizer‐Functionalized Polymetallic Nanoenzymes for Photoacoustic Imaging‐Guided Cancer Sonodynamic Immunotherapy
Low tumor immunogenicity and limited immune‐cell infiltration remain major barriers to effective breast cancer immunotherapy. Although sonodynamic therapy (SDT) offers a noninvasive strategy for deep‐tissue tumor treatment, its efficacy is often restricted by insufficient reactive oxygen species (ROS) generation and th...
