Gold nanoparticles stabilized by a water-soluble mercapto ligand (sodium 3-mercaptopropionate) were produced by a modified citrate reduction of HAuCl₄. No rigorous cleanliness is needed and the reductant is decomposed to CO₂. Stable aqueous dispersions of gold nanoparticles without any precipitation for several months could be obtained. The particle size can be controlled by the stabilizer/gold ratios. These gold nanoparticles were incorporated successfully into the interlayers of cast films of cationic bilayers by immersion of the film in gold nanoparticle dispersions.
