a Cell viability was determined by CCK-8 assay; b H&E staining of the major organs (heart, liver, spleen, lung and kidney) in healthy female nude mice with or without receiving the N2O-mbs; c the images from a to d show cell in bright field, cell nuclei stained by DAPI, N2O-mbs stained by DiI, and the merged results of the three fluorescence images; scale bar = 50 μm [NS no significance, compared with control group (0 bubbles/mL)]
