Figure 5From: Oxidative stress mediated cytotoxicity of biologically synthesized silver nanoparticles in human lung epithelial adenocarcinoma cell lineSize distribution analysis by dynamic light scattering (DLS). Biologically synthesized silver nanoparticles (bio-AgNPs) and chemically synthesized silver nanoparticles (chem-AgNPs) were dispersed in deionized water and DMEM media with and without serum. The particles were mixed thoroughly via sonication and vortexing, and samples were measured at 25 μg/ml.Back to article page
