Research chemists at Northwestern University’s Institute for Sustainability and Energy have engineered cup-shaped molecules from corn that can grab and neutralize carcinogens in our water supply. Very low concentrations of the carcinogens can significantly increase the risk of cancer. For example, just a few drops of the carcinogens, containing millions of potentially cancer-causing molecules, in a volume of water found in an Olympic-sized swimming pool can cause trouble. The molecular catcher’s mitts are equally small: Millions of them can fit into a space the size of a sugar-cube. Filters equipped with the breakthrough material remove the carcinogens from water more effectively than commonly used activated carbon filters, and the filters can be reused after a simple washing step that takes place at room temperature. The researchers have started a company, CycloPure, to commercialize this material for home and institutional use. Now that’s a use of corn that nobody saw coming. This innovation is another example of the extraordinary ingenuity of Chicago-area scientists who are developing technologies that matter.
