We prepared gold nanoparticles (Au NPs) by reduction-oxidation reaction between HAuCl 4 and trisodium citrate and measured the size and morphology of Au NPs by TEM for various molar ratios of HAuCl4 to citrate and for various concentrations of HAuCl4. UV-vis spectroscopy was used to characterize the optical properties of Au NPs. Au NPs in the size range from 14.3 nm to 20.3 nm were prepared with monodisperse distribution.
