Spray-On Liquid Glass 293

bLanark writes with news of a new substance that can be sprayed on for a durable, easy-to-clean film on almost any substance, hard or soft. The liquid glass is essentially pure silicon dioxide, and it goes on in a layer 15 to 30 atoms thick. It is breathable and flexible, but waterproof and resistant to bacterial growth. The patent is held by a German company, Nanopool, which is in discussion with many parties about a wide range of uses: keeping public spaces sanitary, keeping restaurants clean, and keeping cars or trains clean. "The spray forms a water-resistant layer, meaning it can be cleaned using only water. Trials by food-processing companies showed that sterile surfaces covered with a film of liquid glass were equally clean after a rinse with hot water as after their usual treatment with strong bleach."
