Effects of the Absorption Behaviour of ZnO Nanoparticles on Cytotoxicity Measurements

Figure 5

The interference of ZnO nanoparticles (85.7 nm) in absorbance reading in (a) lung cancer, (b) normal lung, and (c) neuroblastoma cells. Control represents untreated cell lines. Black bars represent cell lines treated with Z1 followed by MTS addition. Gray bars represent cell lines treated with Z1 followed by disposing ZnO and addition of MTS (corrected reading). 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).
