The synthesis of gold nanoparticles was investigated via the laboratory preparation of the precursor from the precipitated gold using sodium cyanide (NaCN) and cyanide solution from cassava. Characterization studies are carried out using TEM and XRD. The synthesis of gold nanoparticles was carried out using citrate reduction method as modified for the purpose of this research. TEM images reveal that spherical shaped and well-dispersed gold nanoparticles in the size range between 18 nm – 24 nm were produced successfully. The XRD confirm the crystallinity of the gold nanoparticles.
