•Ultrasound is a biofavorable mechanical wave with broad application potentials.•Various ultrasound-responsive matters have been explored.•These advanced matters have bight future in multidisciplinary fields. Ultrasound (US) is a biofavorable mechanical wave that has shown practical significance in biomedical fields. Due to the cavitation effect, sonoluminescence, sonoporation, pyrolysis, and other biophysical and chemical effects, a wide range of matters have been elucidated to be responsive to the stimulus of US. This review addresses and discusses current developments in US-responsive matters, including US-breakable intermolecular conjugations, US-catalytic sonosensitizers, fluorocarbon compounds, microbubbles, and US-propelled micro- and nanorobots. Meanwhile, the interactions between US and advanced matters create various biochemical products and enhanced mechanical effects, leading to the exploration of potential biomedical applications, from US-facilitated biosensing and diagnostic imaging to US-induced therapeutic applications and clinical translations. Finally, the current challenges are summarized and future perspectives on US-responsive matters in biomedical applications and clinical translations are proposed.
