Abstract
Bio-synthesized nanoparticles (NPs) having reduced chemical toxicity have been focused globally and become essential component of nanotechnology recently. In the study reported here, silver/iron oxide nanocomposite (Ag/Fe2O3) was biosynthesized from ginger oil via a green, economic, and eco-friendly strategy. The biosynthesized Ag/Fe2O3 were characterized using ultraviolet visible (UV-Vis), Fourier transform infrared (FTIR), X-ray diffraction (XRD), transmission electron microscope (TEM), dynamic light scattering (DLS), and scanning electron microscope/energy-dispersive X-ray (SEM-EDX) analysis. The particulates showed a spherical-morphology and had sizes between 44 and 200 nm. Ag/Fe2O3 FTIR analysis revealed functional groups that were analogous to organic metabolites, which reduced and stabilized the nanocomposite. Antimicrobial efficacy of the biosynthesized Ag/Fe2O3 against bacterial pathogens was assessed. In addition, Ag/Fe2O3 exhibited broad spectrum activities against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa with inhibition zones 22.6 +/- 1.15, 21.1 +/- 1.44, 18 +/- 1 and 17.4 +/- 2.67 mm, respectively. The Ag/Fe2O3 showed promising antibacterial action against human bacterial pathogens, making them useful in the medical field.
