focused ultrasound
Delivery StrategyFocused ultrasound (FUS) is a noninvasive physical delivery and control modality that penetrates deep biological tissues and induces confined mild hyperthermia to activate heat-sensitive genetic modules. In the cited 2023 study, FUS was coupled to heat-sensitive CRISPR, CRISPRa, and CRISPRi systems to enable remote spatiotemporal regulation of genome and epigenome function in live cells and animals.
