Ecofriendly synthesis and applications of silver nanoparticles

Abstract

Synthesis of nano materials using novel and ecofriendly methods is under expedition. A novel green route method has been adopted for the preparation of silver nanoparticles, using Abelmoschus esculentus (Okra) juice as a natural binder. XRD, FTIR, UV-Vis, FE-SEM and TEM have been employed for characterization. UV-Vis analysis of the nanomaterial gave a peak at 445nm indicating a successful green route synthesis. FTIR analysis showed the presence of bands at 446, 497, 599, 922, 1036, 1117, 1200, 1383,1600,1774,2928, 3296 and 3561 cm-1 . Field emission scanning electron microscopy and Transmission electron microscopy reported spherical shape of the prepared silver nanoparticles. Antibacterial studies have been carried out by diffusion (cup plate) method for Escherichia coli, Staphylococcus Aueus and Cadida, which showed positive results against these bacteria.
