Nanosized Zinc Oxide Induces Toxicity in Human Lung Cells
Figure 3
Time-dependant ROS generation by ZnO-NPs in L-132 cells. DCF-fluorescence intensity in L-132 cells after exposure to 5, 25, 50, and 100 μg/mL of ZnO-NPs for different time periods, namely, 6, 12, and 24 h. Values were the mean ± SD from three independent experiments. Significance was indicated by versus control.
