Abstract Sonodynamic therapy (SDT) as an emerging modality for malignant tumors mainly involves in sonosensitizers and low-intensity ultrasound (US), which can safely penetrate the tissue without significant attenuation. SDT not only has advantages including high precision, non-invasiveness, minimal side effects, but also overcomes limitation of low penetration light to deep tumors. The cytotoxic reactive oxygen species be produced by utilization combined with US kill tumor cells. However, underlying mechanism been elucidated, its unsatisfactory efficiency retards further clinical application.
