Nanosized Zinc Oxide Induces Toxicity in Human Lung Cells
Figure 2
Phase contrast microscopic images of L-132 cells stained with Leishman’s stain. The cells were cultured with (a) DMEM medium only (control), (b) 5 μg/mL ZnO-NP, (c) 25 μg/mL ZnO-NP, (d) 50 μg/mL ZnO-NP, and (e) 100 μg/mL ZnO-NP. Arrows indicate shrinkage and rounding of cells. The magnification was 200x.
