Gold coated particles tend to be required by academics and specialist facilities for high level research activities. The surface plasmon phenomena associated with gold, as well as its electron density, conductivity and reflectivity means there are a variety of research areas which can utilise this type of material.  As gold lends itself to the electroless plating technique used by MTL, the company has the technology to produce and offer these low volume, high value products on either solid or hollow glass cores.
