Sponge-like “Swelling Glass” absorbs toxins in contaminated water

A new glass has been developed that swells up like a sponge to clean contaminated groundwater. A company called Absorbent Materials has used nanotechnology to create a nanobot particle made from glass that can absorb pollutants from dirty water. The glass particles act like sponges by attracting and binding contaminants to themselves and expanding eight times in size during the process. However, unlike a sponge, these nanobots are hydrophobic, meaning they don't absorb water. This new s...
