Narrator: This is Science Today. A University of California, Davis researcher has developed a product that will score points in locker rooms and homes alike - odor-free, cotton socks. Gang Sun, a professor in the Division of Textiles and Clothing took non-toxic chlorine molecules and bonded them to cotton fibers. Unlike some antibacterial products on the market, Sun says chlorine can kill germs without generating resistance.
Sun: It's different from the antibiotics because the antibiotics kills the germs by a kind of biological process. This biological process also can easily generate the resistance from the germs because most of the antibiotics only target one enzyme. If the enzyme changes a little bit, the enzyme survive and the whole germ will survive and also the whole germ will develop the resistance.
Narrator: But there's no known resistance to chlorine.
Sun: Chlorine has been used for almost exactly a hundred years as a drinking water disinfectant. No resistance.
