Figure 4From: Oxidative stress mediated cytotoxicity of biologically synthesized silver nanoparticles in human lung epithelial adenocarcinoma cell lineSize and morphology of AgNPs analysis by TEM. (A). Several fields were photographed and used to determine the diameter of silver nanoparticles (AgNPs). (B). Particle size distributions from transmission electron microscopy images. The average range of observed diameter was 15 nm.Back to article page
