Figure 2From: Hepatic toxicology following single and multiple exposure of engineered nanomaterials utilising a novel primary human 3D liver microtissue modelCytotoxicity in human liver microtissue following a single or repeated exposures of a panel of engineered nanomaterials. The microtissue were exposed to cell medium (control)/or NMs over a period of 360 hr as measured by AK release and measured via ToxiLight™ cytotoxicity assay. Values represent mean ± SEM (n = 3). Single exposure A) ZnO C) Ag E) MWCNT G) TiO2. Repeated exposure (0, 72, 144, 216 and 288 hr) B) ZnO D) Ag F) MWCNT H) TiO2.Back to article page
