High intensity focused ultrasound (HIFU) has been widely used in clinical treatment of cervical cancer for its non-invasiveness and sharp treatment margins with very low complication rates. However, how to intensify the therapeutic efficacy of HIFU by specifically focusing the ultrasound energy on targeting pathological tissues is still a bottleneck for it to realize successful cancer ablation. Herein, a multifunctional organic-inorganic hybrid nanovesicles, by coating ultrathin silica shell on the surface of poly (lactic-co-glycolic
