Sonodynamic Therapy (Sdt) For Cancer Treatment: Advanced Sensitizers By Ultrasound Activation To Injury Tumor

Because of its high tissue penetrative depth, high remote spatiotemporal selectivity, and noninvasive therapeutic features, sonodynamic therapy (SDT) has received much attention in recent years. In the SDT, a tumor-localizing sonosensitizing agent is activated by ultrasound and produces greatly reactive oxygen species (ROS) to kill tumor cells. Sonosensitizers, including some organic/inorganic compounds and micro/nanoscale sonosensitizers, are an important element in SDT. Herein, we will introduce the organic/inorganic sonosensitizers and advanced micro/nanosized sonosensitizers applied in SDT. At the same time, some perspectives and the future challenges of SDT will be discussed in this review.
