Bucky Tubes Induce Oxidative Stress Mediated Cell Death in Human Lung Cells

Figure 3

Cytotoxic effect of BTs NPs in A549 cells by (a) trypan blue dye exclusion assay using automatic cell counter and (b) propidium iodide (PI) uptake method in which cells were stained with PI and analysed by flow cytometer after 6 h and 24 h exposure. Results were expressed as the percentage cell death after exposure of BT relative to control cells and were represented as mean ± SEM of three independent experiments. (, , and when compared to control).
