Sonodynamic therapy with immune modulatable two-dimensional coordination nanosheets for enhanced anti-tumor immunotherapy

Ultrasound with deep penetration depth and high security could be adopted in sonodynamic therapy (SDT) by activating sonosensitizers to generate cytotoxic reactive oxygen species (ROS). Herein, two-dimensional (2D) coordination nanosheets composed of Zn2+ and Tetrakis(4-carboxyphenyl) porphyrin (TCPP) are fabricated. While exhibiting greatly enhanced ultrasound-triggered ROS generation useful for noninvasive SDT, such Zn-TCPP 2D nanosheets show...
