ABSTRACT

The bio-molecules of various plant components are potentially capable of reducing nanoparticles in their ionic forms. Green synthesis of nanoparticle is the development of simple, inexpensive and, eco-friendly process. This paper presents the green synthesis or bio-synthesis of silver nanoparticles using Putranjiva roxburghii Wall., plant leaf extract as the reducing agent. The study also has confirmed the synthesis of nanoparticles are by color change and it was characterisation by UV-visible spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD). Antibacterial activity of biologically synthesized nanopartilcles against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella paratyphi and Serretia marcescens bacteria was proved. This study, therefore has established showed that the P. roxburghii leaf extract could as a source for the green synthesis of silver nanoparticles with the appropriate antibacterial activity.
