TANAKA Kikinzoku Kogyo K.K announced today that TANAKA has developed gold shell nanoparticles that can be prepared in high concentrations using high dispersion stability. This product is designed to cover the particle surface—such as that of silica—with an extremely thin gold shell that has a thickness of approximately 10 nm. It exhibits strong surface plasmon resonance. Additionally, by using the high dispersion stability in water and polar solvents, it is possible to prepare dispersion liquids with high concentrations that are 100 to 1,000 times that of gold nanoparticles currently being sold on the market.
