Figure 4From: Multidimensional effects of biologically synthesized silver nanoparticles in Helicobacter pylori, Helicobacter felis, and human lung (L132) and lung carcinoma A549 cells Size distribution analysis by dynamic light scattering (DLS). Silver nanoparticles were dispersed in deionized water and the particles were mixed thoroughly via sonication and vortexing, and samples were measured at 25 μg/mL.Back to article page
