a Schematic diagram of the piezocatalytic effect of BT-dNO@Gel under LIFU activation. b–d The NO release profiles under different formulations (b), different BT-dNO@Gel concentrations (c) and different LIFU irradiation durations (d). e XRD pattern of the bare BT and the BT-dNO. f Schematic diagram of the PFM test and the height sensor of BT-dNO. g Piezoresponsive phase and amplitude curves of BT-dNO. h The output voltage signal of BT-dNO and BT-dNO@Gel with or without LIFU irradiation. i The sonocurrent response of BT-dNO and BT-dNO@Gel in the LIFU intensity range of 0–1.5 W cm−2. j The ROS generation capacity under different formulations determined by rhodamine B degradation assays. k, l ESR spectra of ·O2 − (k) and ·OH (l) trapped by DMPO. Data were presented as mean ± SD (n = 3 independent experiments). Statistical significance was determined using a one-way ANOVA test followed by Tukey’s multiple comparison analysis. ns, not significant, *P < 0.05, **P < 0.01 and ****P < 0.0001. Source data are provided as a Source Data file. Elements in (a) were created using templates from BioRender. Li, X. (2026) https://BioRender.com/vfilyre.
