Tiny treasure: The future of nano-gold (Animation) (28 January 2015)
This animation explores how gold nanoparticles could be used to kill cancer cells, improve the efficiency of solar cells and catalyse chemical reactions.
Lumps of gold moulded into rings, coins and ingots have been highly prized for millennia. But recently, scientists have realized that nanoparticles of the metal could also become a valued commodity. In labs around the world, gold nanoparticles are being tested as components in technology and medicines. See how gold could be used to kill cancer cells, improve the efficiency of solar cells and catalyse chemical reactions.
