Concentration of silver inside J774 tumoral macrophage. Cells cultivated in culture bottles exposed to 1000 µg L−1 of pristine silver nanoparticles and graphene oxide-silver nanocomposite for 24 and 48 h. Nanomaterial internalization by cells was estimated by measuring silver concentration ([Ag]) using ICP-MS. (***) p < 0.001. The [Ag] was normalized by the number of cells
