Figure 5From: Multidimensional effects of biologically synthesized silver nanoparticles in Helicobacter pylori, Helicobacter felis, and human lung (L132) and lung carcinoma A549 cells Size and surface morphology of AgNPs analysis by TEM. (A) Several fields were photographed and used to determine the diameter of silver nanoparticles (AgNPs) using TEM. The average range of observed diameter was 20 nm. (B) Histogram of Particle size from transmission electron microscopy images.Back to article page
