Cancer-causing chemicals and drugs like antibiotics pollute many of America’s lakes, rivers and drinking water supplies. Activated carbon filters can remove about 40 percent of carcinogens and antibiotics from these waters. But a tiny solar-powered filter made of two bacterial proteins absorbs more than 50 percent more of the pollutants.
In addition, the filter – developed by a team at the University of Cincinnati – can release the captured antibiotics so they can be reused.
