The cell viability of HeLa cells after 24 h of exposure to ZnO and lipid-coated ZnO NPs. a Control group vs ZnO NPs (~ 7 nm; ~ 18 nm; ~ 49 nm) and lipid-coated ZnO NPs (~ 13 nm; ~ 22 nm; ~ 52 nm); b ZnO NPs (~ 7 nm) vs lipid-coated ZnO NPs (~ 13 nm); c ZnO NPs (~ 18 nm) vs lipid-coated ZnO NPs (~ 22 nm); d ZnO NPs (~ 49 nm) vs lipid-coated ZnO NPs (~ 52 nm). The activity was measured with CCK-8 assay, and the data were expressed as mean ± SD (standard deviation) of three experiments. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
