Gold Nanoparticles 'Can Be Produced Naturally'

". . .gold salts can now be used to manufacture the tiny pieces of the precious metal."
The work by the Asian company may bring environmental benefits to the use of nanotechnology, as natural materials such as plant extracts, soya beans, water and gold salts can now be used to manufacture the tiny pieces of the precious metal.
"Typically, a producer must use a variety of synthetic or man-made chemicals to produce gold nanoparticles," Kenneth Lee, professor of radiology and physics at Ventura Labs in Korea stated.
He added that previous manufacturing of gold nanoparticles relied on the production of artificial chemicals, whereas the new process can have "far-reaching impacts in technology and medicine" due to the fact that it uses natural elements.
Gold nanotechnology was recently used in a cancer treatment technique developed by Massachusetts Institute of Technology (MIT) PhD student Geoffrey von Maltzahn.
