Abstract

This study investigated the role of bis(p-sulfonatophenyl)phenylphosphine (BSPP) in stabilizing gold nanoparticles in 0.5×TBE aqueous solution. Gold nanoparticles were made by the method of reduction of tetrachloroauric acid by sodium citrate, and then they were coated with BSPP. After centrifugation steps, the AuNPs/BSPP kept stable while the AuNPs aggregated without BSPP. When NaCl was added in the solution of AuNPs, with the presence of BSPP, AuNPs/BSPP was stable with little aggregation in a moderate concentration of NaCl. The results showed that BSPP plays an important role in stabilizing gold nanoparticles.
