Abstract

In recent years, green synthesis of nanoparticles has attracted a great attention because of medicine and biological applications. In this work, bismuth oxide nanoparticles (Bi2O3 NP) was prepared via green synthesis using mentha pulegium aqueous extract after 24 h at 90°C. The product was characterized by ultraviolet-visible (UV-VIS) spectrophotometer, Fourier transform infrared (FTIR), X-ray diffraction (XRD), dynamic light scattering (DLS), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and diffuse reflection spectroscopy (DRS). The antibacterial activities of the samples were determined against Salmonella and Escherichia coli (E.Coli) as Gram-negative bacterial and Staphylococcus aureus (S.aureus) as Gram-positive bacterial. The objectives of this study were the green synthesis of bismuth oxide nanoparticles using aqueous extract with a good potential for UV blocking and antibacterial activity. Based on the obtained results, Bi2O3 NPs can have a good candidate for different applications.
