Colloidal Gold nanoparticles have been utilized for centuries by artists due to the vibrant colors produced by their interaction with visible light. The most famous example of which is the Lycurgus Cup from the 4th Century that depicts Ambrosia destroying Lycurgus. The glass in the cup changes from red to green depending on the direction of the light.

 

More recently, these unique optoelectronic properties have been researched and utilized in high technology applications such as organic photovoltaics, sensory probes, therapeutic agents, drug delivery in biological and medical applications, electronic conductors and catalysis. The optical and electronic properties of gold nanoparticles are dependent on the size and shape of the particles.
