Sodium borohydride has been utilized to synthesize Au-NPs as stabilizing agents. The characterization of Au-NPs have been done by different techniques. X-ray diffraction machine has been used to study the structural properties of Au-NPs, which shows that the Au-NPs were in spherical and cubic structure. The surface morphology and the elemental composition of Au-NPs were analysed by SEM attached with the EDAX. UV-visible spectroscopy has been utilized to study the optical properties which shows the absorption peak of Au-NPs at 521nm. The crystallite size of Au-NPs was calculated via Debye-Scherrer and come out to be 12 nm.
