Abstract
In this study, simple method was applied for synthesis of silver nanoparticles using Acalypha wilkesiana aqueous leaf extract. The plant extract acts as bioreducing agent and capping agent. The effects of extract contact time, temperature and concentration on the AgNPs formation were investigated. The data revealed that the rate of formation of the silver nanoparticles increased significantly with increasing time and temperature; and at lower concentration. The nature of AgNPs synthesized was analysed by UV-Visible spectroscopy which showed absorbance peak in range of 450-540 nm. The silver nanoparticles at 0.001 M concentration showed a better inhibition of bacterial growth against Escherichia coli and Staphylococcus aureus than 0.01 M. The results confirmed this procedure as simple, eco-friendly, cost effective and an alternative to conventional physical/ chemical methods without the immersion of any toxic chemical. Thus, AgNPs from extract of Acalypha wilkesiana showed broad spectrum antibacterial activity at lower concentration and may be a good alternative therapeutic approach in future as a substitute for commercial antibacterial therapeutics.
