Synthesis of Ag/Fe2O3 nanocomposite from essential oil of ginger via green method and its bactericidal activity

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/Fe 2 O 3 ) was biosynthesized from ginger oil via a green, economic, and eco-friendly strategy. The biosynthesized Ag/Fe 2 O 3 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/Fe 2 O 3 FTIR analysis revealed functional groups that were analogous to organic metabolites, which reduced and stabilized the nanocomposite. Antimicrobial efficacy of the biosynthesized Ag/Fe 2 O 3 against bacterial pathogens was assessed. In addition, Ag/Fe 2 O 3 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/Fe 2 O 3 showed promising antibacterial action against human bacterial pathogens, making them useful in the medical field.
