ABSTRACT

In the course of the most recent couple of years, the green synthesis of nanoparticles (NPs) using plant parts has developed as a promising procedure for the manufacture of metallic NPs (particularly gold, silver [Ag], zinc oxide, and copper NPs) as it includes a simple, quick, low cost, and ecofriendly. Formation of AgNPs was characterized by ultraviolet (UV)-visible spectroscopy, X-ray diffraction (XRD), energy dispersive X-ray, transmission electron microscopy, and X-ray photoelectron spectroscopy. The biosynthesis of Plumeria obtusa AgNPs (PO-AgNPs) was confirmed utilizing UV-visible spectrophotometer which showed maximum absorbance at 445 nm wavelength. The spherical and face-centered cubic crystalline nature of PO-SNPs was investigated with transmission electronic microscopy and XRD. Biosynthesized AgNPs inhibit the growth of the Gram-positive and Gram-negative bacterial strains.

Key words: Green synthesis, Plant extract, Plumeria obtusa, silver nanoparticles, Antibacterial activity, X-ray photoelectron spectroscopy.
