Now, non-toxic spray that protects any surface against dirt, bacteria

London, Feb 1 (ANI): A non-toxic spray invisible to the human eye that protects against everything from bacteria to UV radiation could soon be used on a vast range of products.

Researchers clam that liquid glass, the revolutionary spray, which is harmless to the environment, can be used to protect against disease, guard vineyards against fungal threats and coat the nose cones of high-speed trains, reports The Telegraph.

The spray, which forms an easy-clean coating one millionth of a millimetre thick - 500 times thinner than a human hair - can be applied to virtually any surface.t is hoped that liquid glass, a compound of almost pure silicon dioxide, could soon replace a variety of cleaning products which are harmful to the environment, leaving our world coated in an invisible, wipe-clean sheen.

The patent for the technology is owned by a German company, Nanopool.

Neil McClelland, Nanopool's UK project manager, told The Independent: "Very soon almost every product you purchase will be protected with a highly durable, easy-to-clean coating ... the concept of spray-on glass is mind-boggling." (ANI)
