Abstract

Gold nanoparticles stabilized by a small mercapto-ligand were assembled by the layer-by-layer alternate adsorption. Due to high chemical stability of these nanoparticles, sodium chloride could be added to the dispersion to reduce the electrostatic repulsion between the particles. Obtained layers of gold nanoparticles showed golden metallic luster and electro-conductivity.
