Abstract
. Among them, ultrasound-responsive hydrogels, as a new class of intelligent hydrogels, have shown irreplaceable application prospects due to their non-invasive, safe, controllable and economical response characteristics. In this review, we summarize the recent advances in ultrasound-responsive hydrogels for biomedical applications. The mechanism and performance of ultrasound-responsive hydrogels in the applications of ultrasound imaging, on-demand drug delivery and shape-memory are presented in detail, respectively, followed by the discussion of the challenges and prospects. The purpose of this review is to provide reference for the interaction between hydrogels and ultrasound for biomedical applications.
