Abstract

The present study is aimed to investigate the synthesis of silver nanoparticles using leaf broth of Hybanthus enneuspermus (Family: Violaceae). The freshly prepared leaf broth of H. enneuspermus was pale yellow in colour and turned to brown within thirty minutes and became dark brown in colour within twenty four hours when exposed to 1mM aqueous silver nitrate. This indicates the synthesis of silver nanoparticles from silver nitrate through bio-reduction. The synthesized silver nanoparticles were characterized by the UV-Visible spectroscopy (UV-Vis), Fourier Transform Infrared spectroscopy (FTIR), X-ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray (EDX) spectroscopy, Transmission Electron Microscopy (TEM) analysis. TEM elucidates the size and shape of the synthesized silver nanoparticles. The size varies between 05 and 30nm with the mean 15±3.38nm. As a green approach and cost effective nature, the leaf broth of H. enneuspermus mediated synthesis of silver nanoparticles becomes an alternative to physical and chemical methods. Further this synthesis protocol becomes an eco-friendly route as it is not involved of any toxic chemicals.
