Schematic overview of ultrasound-triggered gas therapy. Under ultrasound irradiation, the gas released molecules are released gases, for example, NO, O2, CO, CO2, for tumor therapy.

In recent years, ultrasound, as an external stimuli that can activate different types of naonocatalysts for therapy, has attracted extensive attention. One characteristic that makes ultrasound a particularly attractive trigger stimulus for nanomedicine is that it can be applied to the deep regions of the body noninvasively in a focused way. Different biological effects can be achieved by integrating ultrasound with nanocatalysts, and nanodroplets. Gas therapy, as a green antitumor treatment, has attracted substantial attention. The development of nanotechnology and nanomedicine has made gas therapy more precious by controlled release under internal, and outside factors and targeted delivery. In this article, an overview of ultrasound-based gas therapy on antitumor therapy has been provided. First, we explored the mechanism of ultrasound-triggered gas release. Second, we list the common gas release pathways and their mechanism in response to ultrasound activity. Third, exemplary instances of gas-generating facilities under ultrasound controllable are explored, with an emphasis on their originality and guiding principles. The impact of the gas-generating platform as a tumor therapy has also been considered. Finally, the difficulties and future prospects for this effective therapeutic approach are examined.
