Maybe instead of stocking canned food is time to get some land, plant alfalfa and be protected on all fronts.... <<INSIDE TRACK: Plants with a liking for gold By Fiona Harvey Financial Times; Aug 22, 2002 Scientists in the US have found an unusual way to get their hands on tiny particles of gold: they are using alfalfa plants. The plants act as tiny factories, extracting metals from the medium in which they are growing and storing them in their cells. They store gold in particles less than a billionth of a metre across, which is exactly the form in which they are most useful to scientists studying the use of gold in nanotechnology, for instance in the creation of new semiconductor devices. Conventional methods of producing nanoparticles require cocktails of harsh chemicals, and can be costly and cumbersome. If plants can be made to manufacture particles of the required size, production should be much cheaper. By lacing with gold the medium in which the plants are growing, it is possible to encourage them to store the metal. The scientists are now seeking efficient ways to extract the particles from the alfalfa. Stanford University, California, US; tel: 00 1 650 723 2300; www.stanford.edu
