Abstract

In this paper, we synthesized the spherical gold nanoparticles (AuNPs) of 70 nm size, using HAUCL solution and the aqueous extract of Fenugreek plant seeds, which can act as a reducing, stabilizing and capping agent, at ambient condition. The formation of gold nanoparticles was confirmed by the first exciton peak of UV Vis. Spectra that was supported by the change in color of the solution. As synthesized Au, nanoparticles were characterized with the help of UVVis absorption spectroscopy analysis, Fourier Transform Infrared (FTIR) analysis, and Scanning Electron Microscopy (SEM) analysis.

Keywords: Gold, nanoparticles, Fenugreek, plant, seeds.
