a Fluorescence spectrum of SOSG with N2O-mbs irradiated by LIFU; b cell viability was determined by CCK8 assay; c confocal images of intracellular ROS generation (green fluorescence indicates positive staining for ROS stained with DCFH-DA); d the average fluorescence intensity value (DCFH-DA) of each group calculated by Image J. (The data were shown as mean ± SD, n = 5 per group, *p < 0.05, compared with LIFU–C3F8-mbs group)
