Abstract
The self-assembly and the surface seeding methods to prepare gold (Au) shell on polystyrene (PS) latex beads were described. The Au-shell formation was based on the increase of gold coverage by reaction with NH2OH and HAuCl4. The formation of Au clusters and 'streaky' gold nanoparticles on the surface of the PS beads were demonstrated using transmission electron microscopy. It was indicated that polyethylenimine polymer chains were stretched out on the surface of PS beads and one-layer SiO2-coated Au/PS particles were prepared.
