The wide and frequent use of engineered nanomaterials (NMs) raises serious concerns about their safety for human health. Our aim is to evaluate the embryotoxic potential of silver, uncoated and coated zinc oxide, titanium dioxide and silica NMs through the embryonic stem cell test (EST). EST is a validated in vitro assay that permits classification of chemicals into three classes (non, weakly or strongly...
In this work in situ proliferation of A549 human lung epithelial carcinoma cells exposed to nanomaterials (NMs) was investigated in the presence or absence of 10% serum. NMs were selected based on chemical composition, size, charge and shape (Lys-SiO 2 , TiO 2 , ZnO, and multi walled carbon nanotubes, MWCNTs). Cells were treated with NMs and 4h later, cytochalasin-B was added. 36h...
