Screening of antibacterial potential of biosynthesized silver nanoparticles by using some medicinal plants

The Silver nanoparticles (AgNPs) were biosynthesized from the leaf extracts of Prunus Dulcis & Syzygium Cumini by ecofriendly means. In this study, rapid, simple approach was applied for synthesis of silver nanoparticles using Prunus Dulcis & Syzygium Cumini aqueous solution and leaf extract. The plant extract acts both as reducing agent as well as capping agent. To identify the compounds responsible for reduction of silver ions, the techniques used to characterize synthesized nanoparticles are UV-Visible spectrophotometer. UV-Visible spectrophotometer showed absorbance peak in range of 400nm & 422nm and 400nm. The silver nanoparticles showed antibacterial activities against Escherichia coli (MTCC1679) microorganisms. Results confirmed this protocol as simple, rapid, one step, and eco-friendly, nontoxic and alternative conventional physical/chemical methods. only 24hrs. were required for the conversion of silver ions into silver nanoparticles at room temperature, without the involvement of any hazardous chemical.
