In 1850 Farraday discovered colloidal compounds of gold and chlorine. Today gold nanoaparticles are used in industry. Applications include as superconductors, and in drug delivery systems. Gold nanoparticles can combine with cancer cells. But these particles had not been seen. Rob Hough went looking, and has been able to see the surfaces of naturally occurring gold crystals. This has generated interest from manufacturers around the world.
