In this study, gold nanoparticles (GNPs) with different sizes and shapes were synthesised by seed-mediated method. The nano-seeds were synthesised by the Turkevich method and presented an average diameter of 17.6 nm. Different reducing agents such as hydroquinone (HQ), ethylenediaminetetraacetic acid (EDTA), and protecting agents such as citric acid (CA), trisodium citrate (TSC) were used in the growth solution with different volumes of seeds solution. The morphology and size of the synthesised GNPs were characterised by UV-Vis spectrophotometry, transmission electron microscopy (TEM) and scan electron microscopy (SEM). We obtained colloidal GNPs with diameters ranging from 32.1 nm to 509.2 nm.
