Abstract

To understand the genotoxicity induced in the liver by silver nanoparticles (AgNPs) and silver ions, an engineered gold nanorod core/silver shell nanostructure (Au@Ag NR) and humanized hepatocyte HepaRG cells were used in this study. The involvement of oxidative stress and cell cycle arrest in the DNA and chromosome damage induced by 0.4-20 µg mL

Keywords: Cell cycle arrest; Genotoxicity; Gold nanorod core/silver shell nanostructures; HepaRG cells; Oxidative stress; Silver ions
