In vivo piezocatalytic therapy on tumor regression under US irradiation. Time-dependent body-weight curves (Panel A), and time-dependent tumor-growth curves of tumor-bearing mice after different treatments, including control group, Gel group, T-BTO-Gel group, Gel + US group, and T-BTO-Gel + US groups (*p < 0.05, **p < 0.01, ***p < 0.001) (Panel B). Schematic illustration of piezocatalytic therapy in vivo (Panel C). Digital photos of 4T1-tumor- bearing mice and their tumor regions after various treatments at different intervals (Panel D). Survival curves of tumor-bearing mice after treatment (Panel E). Reprinted with permission from Advanced Materials,
