Cytotoxic Effects of Biosynthesized Zinc Oxide Nanoparticles on Murine Cell Lines

Figure 6

Cell cycle analysis of WEHI-3B cells treated with ZnO-NPs after staining with PI. (a1)–(c1) untreated WEHI-3B cells for 24, 48, and 72 h, respectively. (a2)–(c2) the effects of 24, 48, and 72 h, respectively, relative to exposure of WEHI-3B cells to ZnO-NPs. G0/G1, G2/M, and S indicate the cell phase, and Sub-G0-G1 refers to the apoptotic cells.
