Description
Summary:Development of reliable method for the green synthesis of gold nanoparticles (AuNPs) using medicinally valued Adhatoda vasica Nees has been studied here. The color change and the Surface Plasmon Resonance (SPR) confirmed the formation of AuNPs. The biosynthesized AuNPs were characterized using UV-visible Spectroscopy (UV-vis), Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDAX) and Transmission Electron Microscopy (TEM) analysis. The nanoparticles synthesized were predominantly monodisperse, stable spherical in nature with well-defined dimensions of size ranging from 22 to 47 nm. The crystalline nature of the synthesized particles was also evident by the X-ray diffraction analysis.
