Silver nanoparticles prepared by colloid assisted biofabrication methodology using soilless-grown Moringa oleifera in Armenia

In this study, green synthesis assisted colloidal solution system was used to prepare monodispersed spherical silver nanoparticles from hydroponic Moringa oleifera Lam. leaf extract. The Moringa oleifera leaf extract used has shown great potential in the biosynthesis of silver nanoparticles for medicinal and biotechnological applications. The formation of silver nanoparticles was observed by UV-Vis spectroscopy with a surface plasmon resonance band at 425 nm after 1 hour of preparation. Transmission electron microscopy (TEM) imaging shows that the nanoparticles are spherical in shape with an average size of 20 nm. The atomic force microscopy (AFM) image showed that the Ag nanoparticles were spherical with good monodispersity, confirming the TEM results. The biomedical use of the green synthesized silver nanoparticles from medicinal plants as antimicrobial and cytotoxic agents can be suggested by their strong bioactivity and synergistic effect of Moringa oleifera and silver nanoparticles.
