abstract = "The toxic effects of ZnO nanoparticles (nano-ZnO) (1100 g/mL) suspended in DMEM were examined in human A549 cells, HepG2 cells, human skin fibroblast cells, human skin keratinocytes, and rat primary neuronal cells for 24 h. Nano-ZnO induced dose dependent cytotoxicity
and damaged cell membranes. Cell death was not mediated by reactive oxygen species (ROS) or apoptosis. Nano-ZnO induced DNA damage in rat primary neuronal cells, human fibroblasts, and A549 cells. The cytotoxicity of nano-ZnO in DMEM supplemented with 10% FBS, instead of serum free DMEM, was
also examined in the A549 cells, human skin fibroblast cells, and human skin keratinocytes. The levels of cytotoxicity induced were similar to those tested without FBS; in addition, ROS was observed. These results indicate that the cause of cytotoxicity is medium dependent and imply that cellular
growth conditions may play a significant role in induction of cytotoxicity and DNA damage by nano-ZnO.",
