Outline of Final Research Achievements

We have synthesized gold-silica (and silver-silica) yolk-shell nanoparticles. The synthesis is based on a novel technique which is developed from our earlier method for silica hollow nanoparticles (J. Am. Chem. Soc. 2007, 129, 1534). We have succeeded in obtaining gold-silica (and silver-silica) yolk-shell nanoparticles. However, the yields of the yolk-shell nanoparticles are low for both gold-silica and silver-silica cases. We have tried to increase the yields by several modifications such as changing a template polymer. However, the yields have not been improved significantly. It seems necessary to increase the amount of the adsorbed template polymers on the core (yolk) nanoparticles to increase the yields of the yolk-shell nanoparticles.
