Nanoparticles exhibit different properties based on their chemical composition, shape, and size. Uniform, quasi-spherical gold nanoparticles were synthesized using a modified Frens method with chloroauric acid and trisodium citrate and glutathione as ligands. The goal of this research was to study the optical properties of these gold nanoparticles and utilize them for optical trapping studies. During the synthesis, trisodium citrate concentration, tris buffer concentration, and temperature were manipulated to stabilize the nanoparticles, increase uniformity, and decrease particle size. In addition, glutathione (GSH) was used as a second ligand to further decrease the nanoparticle size. The results of the work as a function of GSH, citrate ion and tris concentrations will be presented.
