Опубликована: Окт. 16, 2020

Ultrasound (US)-triggered sonodynamic therapy (SDT), as a promising noninvasive therapeutic modality, has received ever-increasing attention in recent years. Its specialized chemical agents, named sonosensitizers, are activated by low-intensity US to produce lethal reactive oxygen species (ROS) for oncotherapy. Compared with phototherapeutic strategies, SDT provides many noteworthy opportunities and benefits, such deeper penetration depth, absence of phototoxicity, fewer side effects. Nevertheless, previous studies have also demonstrated its intrinsic limitations. Thanks the facile engineering nature nanotechnology, numerous novel nanoplatforms being applied this emerging field tackle these barriers achieve continuous innovations.
