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.

具有降低化学毒性的生物合成纳米粒子 (NPs) 已成为全球关注的焦点，并成为最近纳米技术的重要组成部分。在这里报道的研究中，银/氧化铁纳米复合材料 (Ag/Fe ₂ O ₃ ) 是通过绿色、经济和环保的策略从姜油中生物合成的。采用紫外可见光 (UV-Vis)、傅里叶变换红外 (FTIR)、X 射线衍射 (XRD)、透射电子显微镜 (TEM)、动态光散射 (DLS) 和扫描对生物合成的 Ag/Fe ₂ O ₃进行了表征电子显微镜/能量色散 X 射线 (SEM-EDX) 分析。颗粒呈球形，尺寸在 44 至 200 nm 之间。银/铁₂ O ₃FTIR 分析揭示了类似于有机代谢物的官能团，可减少和稳定纳米复合材料。评估了生物合成的 Ag/Fe ₂ O ₃对细菌病原体的抗菌功效。此外，Ag/Fe ₂ O _3对金黄色葡萄球菌、枯草芽孢杆菌、大肠杆菌和铜绿假单胞菌具有广谱活性，抑菌圈分别为 22.6 ± 1.15、21.1 ± 1.44、18 ± 1 和 17.4 ± 2.67 mm。Ag/Fe ₂ O ₃显示出对人类细菌病原体的有希望的抗菌作用，使其在医学领域有用。
