Genotoxicity mechanism
WebJul 29, 2024 · The genotoxicity of nanomaterials has attracted great attention in recent years. As a possible occupational carcinogen, the genotoxic effects and underlying mechanisms of titanium dioxide nanoparticles (TiO2 NPs) have been of particular concern. In this study, the effect of TiO2 NPs (0, 25, 50 and 100 µg/mL) on DNA damage and the … WebGenotoxicity mechanism has also been discussed in detail with a wider perspective. Genotoxicity testing has been discussed with subsections taking into consideration the performance enhancement of in-vitro genotoxicity testing. This book defines appropriate strategies about advances in in-vivo genotoxicity testing, which have been listed along ...
