Effects of the Absorption Behaviour of ZnO Nanoparticles on Cytotoxicity Measurements

Figure 6

The absorbance measurements without MTS reagents in different cell lines. Control represents untreated cell lines. Cells were treated with Z1 for 24 h. Black bars represent measurements in the absence of MTS. 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).
