Influence of mercaptan chain length on the stability of gold nanoparticles

  • Spherical gold nanoparticles (GNPs) of approximately 20 nm were synthesized using the hydroquinone reduction HAuCl4 method and modified GNPs using the alkyl mercaptan with different chains (ethyl mercaptan,butyl mercaptan,1-hexyl mercaptan, n-octyl mercaptan, dodecyl mercaptan and octadecyl mercaptan). The particles have been characterised by UV-vis spectrophotometer, high resolution transmission electron microscopy (TEM) and Zeta potential analyzer. The results showed that with the increase of alkyl length,the GNPs become stability under the same concentration conditions.
