Pancatalytic tumor therapy by ultrasound activation of inorganic sonosensitizers

Abstract

Pancatalytic therapy (PCT) is a comprehensive framework for disease management through the holistic control of catalytic and quasi-catalytic processes, including preparation (P) of catalysts, activation (A) of specific bio-effects and nontoxic-treatment (N) of different diseases. Ultrasound (US)-activated inorganic sonosensitizers have emerged as a powerful platform for pancatalytic tumor therapy, enabling precise and non-invasive cancer treatment through localized reactive oxygen species (ROS) generation by the specific sonocatalytic mechanism. Upon exposure to US activation, inorganic sonosensitizers generate electron-hole pairs that produce sonocatalytic effect, generating cytotoxic ROS to induce oxidative damage in tumor cells. With ongoing advances in nanomaterial design and US technology, inorganic sonosensitizers represent a transformative approach for precision oncology, offering a versatile and clinically translatable solution for the emerging pancatalytic tumor eradication. This comprehensive review summarizes and highlights recent developments in different kinds of inorganic sonosensitizers and their specific application for pancatalytic tumor therapy. This review begins with providing an overview of inorganic sonosensitizers. The focus is then shifted to US-activated pancatalytic tumor therapy with high therapeutic efficacy. The biosafety and biospecificity of US-activated sonosensitizers on combating tumor were further discussed. Finally, the critical challenges and perspectives on potential directions for future clinical translation of this technology are presented.
