However, chemistry postgraduate student Zhichang Liu has discovered -- by accident -- a new method of extracting gold, using (of all things) corn starch instead of cyanide. It could eliminate the need for an extremely damaging industrial practice around the world.
Liu was part of a team led by Sir Fraser Stoddart at Northwestern University, Illnois that was looking for something quite specific -- three-dimensional cubes made of gold and starch that could be used to store tiny bubbles of gas and other molecules. In the kind of chemistry experiment you can even try at home, Liu mixed two solutions together at room temperature in a beaker -- a gold-bromide solution, and a solution of sugary starches known as cyclodextrins, which are made up of rings of glucose molecules.
