Potent antibacterial action of phycosynthesized selenium nanoparticles using <i>Spirulina platensis</i> extract

Abstract Selenium nanoparticles (SeNPs) are reinforced safe forms of the essential micronutrient selenium (Se) which take a lead in countless biotechnological and biomedical applications. The phycosynthesis SeNPs was successfully investigated using cell-free extract microalgae, Spirulina platensis. phycosynthesized S. platensis -SeNPs ( Sp SeNPs) were characterized several characterization techniques such as UV-Visible, transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, energy dispersive X-ray. They effectually achieved different concentration from sodium selenite (Na 2 SeO 3 ) (1, 5, 10 mM) to give size means 12.64, 8.61, 5.93 nm, respectively, with spherical shapes highly negative zeta potentialities. analyses revealed involvement many phycochemials production. antibacterial properties confirmed, qualitatively quantitatively, against foodborne microorganisms Staphylococcus aureus Salmonella typhimurium ); activity correlated increased SeNPs’ diminution. scanning micrographs cells treated indicated severe action destroy bacterial time-dependent manners. innovative facile is recommended generate effectual bioactive agents control hazardous species.
