Cytotoxicity of nanomaterials to J774 tumoral macrophages and peritoneal macrophages from Balb/c mouse. The number of viable tumoral macrophages was determined by trypan blue exclusion assay. The percentage of peritoneal macrophages adhered to the coverslips was determined after exposure to nanomaterials. Pristine graphene oxide (a, b), pristine silver nanoparticles (c, d), and graphene oxide-silver nanocomposite (e, f) after 24 and 48 h of exposure. Differences in the cytotoxicity of nanomaterial concentrations were determined compared to control cells (*) p < 0.05. MØ macrophage
