Effects of the Absorption Behaviour of ZnO Nanoparticles on Cytotoxicity Measurements

Figure 9

(a) Cytotoxicity effects of ZnO nanoparticles Z1 (85.7 nm) and Z2 (190 nm) in SH-SY5Y cells; (b) neurotoxicity effects of Z1 and Z2 on cell viability in differentiated SH-SY5Y cell lines after 24 or 96 h incubation. 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).
