Biosynthesis of Silver Nanoparticles from Rhododendron arboreum for Metal Sensing, Antibacterial Assessment, and Photocatalytic Degradation

Figure 9

Antibacterial activity of Ag NPs against S. aureus and E. coli synthesized from R. arboreum. The activity was measured (Table S4) in terms of zone of inhibition (ZOI) with the standard antibiotic neomycin (center), distilled water (1), plant extract (2), and Ag NPs (3) using the disc diffusion method.
