This work reports the biosynthesis of highly stable silver (Ag) nanoparticles (NPs) by using leaf extract of Moringa oleifera (Drumstick) for an enhancement of antibacterial and photocatalytic effects. The optical and structural properties of the synthesized sample have been studied by various comprehensive techniques. These studies confirm the formation of well crystalline and stable biogenic Ag NPs. The green synthesized Ag NPs are found to exhibit ultrahigh antibacterial effects against both the Gram-negative and Gram-positive bacteria as estimated by agar well diffusion method. The photocatalytic activity of this sample was also performed by studying the UV–Visible absorption spectra of a common dye, methylene blue (MB) under direct sunlight irradiation. Based on this study, the biosynthesized Ag NPs can find applications in textile industry, treatment of waste water, and safe biomedical purposes due to its high photocatalytic activity and ultrahigh antibacterial efficiency.
