ABSTRACT

Ultrasound (US) is a promising external excitation modality for bioapplications, offering significant advantages over X-rays or laser, due to its low cost, high biosafety, and ideal tissue penetration depth. US-activated theranostic materials, comprising organic, inorganic, and hybrid-based compounds-hold particular value in synergistic cancer therapeutic and diagnostic applications. These materials exhibit excellent imaging properties, high drug delivery and release efficiency, and enhanced ROS production, making them suitable for clinical diagnostic imaging and therapeutic interventions. This review summarizes recent research on the design, performance, and optimization of US-mediated molecules/nanosystems for a wide range of biomedical applications. Additionally, the multifunctional use of these sonosensitizers in imaging, drug delivery, and sonodynamic therapy, especially in combination with other treatment could pave the way for innovative strategies in disease therapy. Finally, an overview of this field's challenges and potential future directions is provided, highlighting pathways to promote clinical translation and application.
