Effects of the Absorption Behaviour of ZnO Nanoparticles on Cytotoxicity Measurements

Figure 8

Cytotoxicity effects of ZnO nanoparticles, Z1 (85.7 nm) and Z2 (190 nm), after 24 or 96 h incubation in (a) lung cancer cell lines (A549) and (b) normal lung (Hs888Lu) cells. Control represents untreated cell lines. Values are means ± SD (𝑛=3) and all comparisons were made using two-tailed Student’s t-test (^∗𝑃<0.05; ^∗∗𝑃<0.01; ^∗∗∗𝑃<0.001).
