 Ultrasound-triggered drug delivery using stimuli-responsive hydrogels

Ultrasound-triggered drug delivery using stimuli-responsive hydrogels is an innovative approach in the field of controlled drug delivery systems. This technique involves the use of hydrogels that respond to external stimuli—in this case, ultrasound waves—for the controlled release of therapeutic agents. ### Key Components: 1. **Hydrogels**: These are three-dimensional polymer networks that can retain a significant amount of water while maintaining their structure.
