Green Synthesis and Antibacterial Activity of Ag/FeO Nanocomposite Using Extract.

In the study reported in this manuscript, silver/iron oxide nanocomposites (Ag/FeO) were phytosynthesized using the extract of via a green, economical and eco-friendly strategy. The biosynthesized Ag/FeO nanocomposites were characterized using UV-Vis spectrophotometry, FTIR, XRD, TEM, DLS and SEM-EDX analyses. The particulates showed a triangular and spherical morphology having sizes between 25 and 174 nm. FTIR studies on the nanoparticles showed functional groups corresponding to organic metabolites, which reduce and stabilize the Ag/FeO nanocomposite. The antimicrobial efficacy of the phytosynthesized Ag/FeO against bacterial pathogens was assessed. In addition, Ag/FeO exhibited broad spectrum activities against , , , and with inhibition zones of 23.4 ± 0.75, 22.3 ± 0.57, 20.8 ± 1.6, and 19.5 ± 0.5 mm, respectively. The Ag/FeO composites obtained showed promising antibacterial action against human bacterial pathogens (, , and ), making them candidates for medical applications.
