Description
Summary:•Silver-doped selenium nanoparticles (Ag/SeNPs) were synthesized using Muntingia calabura leaves extract, which has bioactivity compounds such as flavonoids and polyphenols.•Ag/SeNPs is smaller (220 nm) in size and higher stability (–44.5 mV) in Zeta potential than pure SeNPs.•Ag/SeNPs demonstrated enhanced antibacterial activity against Escherichia coli and Staphylococcus aureus, and antifungal activity against Fusarium oxysporum. In this study, silver-doped selenium nanoparticles (Ag/SeNPs) were synthesized using Muntingia calabura leaves extract. The extract components, such as flavonoids and polyphenols, acted as both reducing and stabilizing agents and were quantified to confirm their presence. The properties of Ag/SeNPs were examined using advanced analytical techniques such as Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), field-emission scanning electron microscopy (FE-SEM), zeta potential measurement, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The antibacterial activity of the Ag/SeNPs was tested against Escherichia coli and Staphylococcus aureus, which show good antibacterial ability with inhibition zone diameters of 9.1 and 11.7 mm, respectively. Moreover, Ag/SeNPs also demonstrate superior antifungal capability against Fusarium oxysporum compared to SeNPs. The results indicate that Ag/SeNPs were synthesized using the green method demonstrate significant potential for medical applications. [Display omitted]
