Synthesis and Characterization of Gold Nanoparticles

In this paper, Gold Nanoparticles (GNPs) has been successfully prepared by chemical reduction method (TERKEWISH method) using Sodium Citrate as reducing agent and by Green method using Fructose as reducing agent. The synthesized gold colloidal solution is characterized by using ZETA POTENTIAOMETER, FTIR and UV-VIS spectroscopy. Results of zeta shows that GNPs with sodium citrate have particle size of 119.5 nm (diameter) and have incipient stability. GNPs made with green method using fructose have particle size 50 nm (diameter) and have moderate stability. Results of FTIR are in good agreement to that has been explained in literature. Results of UV- VIS shows that GNPs with sodium citrate gives peak at 526 nm and GNPs made with green method using fructose gives peak at 520 nm, these results match with literature reviews
