fornia at Berkeley announced that they could control chemical reactions molecule by molecule. "The key to the technique is to put a dab of platinum on the microscopic tip of an atomic force microscope. (The tip of such a microscope is a tiny cantilever that rides like a phonograph needle just above the surface of a sample and reacts to forces exerted by the electrons beneath it.)" The Platinum acts like a catalyst, stimulating a reaction between two reactants, just stimulating a reaction one molecule at a time. The molecules are stimulated in a pattern giving the desired results. This discovery opens doors for nanoengineering and material sciences. It gives a good view of what happens, one molecule at a time. Chemical reactions are a large part of chemistry. Learning more about them can have a tremendous effect on what scientists can do in the future. By studying how to manipulate them to make certain products that could revolutionize the world....
