A The viability of HEK239T cells treated with PB NZs for 24 and 48 h, respectively. B Representative confocal fluorescence microscopy images of cellular ROS levels detected by DCFH-DA staining under different indicated treatment conditions. The scale bar is 20 μm. C Relative ROS levels in HEK293T cells incubated with 0.5 mM H2O2 under different indicated treatment conditions. Fluorescence images (D) and corresponding statistical histograms (E) of intracellular NO levels under different conditions. The scale bar is 5 μm. Fluorescence images (F) and corresponding statistical histograms (G) of intracellular ONOO− levels under different conditions. The scale bar is 5 μm. H Viability of HEK293T cells after treatment with 0.5 mM H2O2 or different concentrations of PB NZs. A scatter diagram (I) and a histogram (J) of cell apoptosis and necrosis distribution in untreated and PB NZs-treated HEK293T cells
