Synthesis And Charectarization Of Silver Nanoparticle From Emilia Sonchifolia (L) Leaf Extract And Their Antibacterial Assay

Nanoparticles are fundamental building blocks of nanotechnology. An eco-friendly approach for green synthesis of nanoparticles using natural plant extract is gaining a notable importance now a days. The present study deals with the synthesis of silver nanoparticles using Emilia sonchifolia(L) leaf extract. The complete reduction of silver ions was observed after 48hrs of reaction at 30°C under shaker condition. The formation of silver nanoparticles was confirmed by UV-VISIBLE spectroscopy, XRD and SEM analysis. The antifungal activity evaluate against Aspergillus niger and cladosporium. The antibacterial activity evaluated against E-coli and Salmonella typhi.
