Biosynthesis of silver nanoparticles using Typha domingensis and study of their biological activity

The Green synthesis method of silver nanoparticles by Typha domingensis was investigated. The aqueous extract prepared from Typha domingensis was evaluated as reducing agent for biosynthesis of silver nanoparticles. The formation of silver nanoparticles was visually monitored with change in colour from yellow to brown and later monitored with UV-Vis spectroscopy. Energy dispersive x-ray spectra (EDS) analysis method shows the qualitative and quantitative analysis of synthesis of silver nanoparticles. The synthesized silver nanoparticles were further characterized by SEM, and were employed in biological study. The results reveal that typha, is capable of synthesizing spherical shaped silver nanoparticles with biological activity.
