Researchers have developed a tiny, solar-powered device that will purify water for drinking in only twenty minutes.
The nanostructured device is about the size of a postage stamp, and looks like a piece of black glass. The surface of the device is etched like a fingerprint, with the ridges made of atoms-thick layers of molybdenum topped with a thin layer of copper. By stacking the molybdenum in a precise way, the team was able to get the material to absorb the full range of visible sunlight. That sunlight was then used to trigger a reaction with the copper, which kills bacteria.
When placed in water and exposed to sunlight, the little device will kill 99.999 percent of bacteria in twenty minutes.
