Figure 1

Cytotoxicity profile of pristine and surfactant-dispersed ZnO NPs after 24 hr exposure of human lung epithelial A549 cells, using the (A) MTS assay and (B) lactate dehydrogenase release assays. Cytotoxicity was dependent on NP size and dispersal state. Concentrations at or below the dotted line (MTS assay) and beyond the dotted line (LDH release assay) were significantly different from untreated control cells. Values are expressed as mean ± SEM (n = 5 separate experiments).
