Abstrakt: Purpose: The solution plasma process (SPP) is a novel electrical discharge process for the green synthesis of nanomaterials, in which an atmospheric nonequilibrium plasma is generated at room temperature in a liquid environment such as water or an organic solvent; or a mixture of both. Methods: In this study, SPP was employed as a green approach for synthesizing selenium nanoparticles (Se NPs) in an ethanol–water solution at room temperature. The prepared Se NPs were comprehensively characterized using ultraviolet–visible (UV–Vis) spectrophotometry, fourier transform infrared spectroscopy, X-ray diffraction, dynamic light scattering particle size analysis, scanning electron microscopy, and transmission electron microscopy. Results: The results showed that the Se NPs in the ethanol–water solution were uniform flower-like nanostructures with diameters ranging from 50 to 100 nm. The as-prepared Se NPs were of high purity and underwent partial oxidation. Conclusion: The synthesized Se NPs exhibited notable antimicrobial properties against the pathogenic Escherichia coli and Staphylococcus aureus bacteria, and Candida albicans yeast.
