It sounds too good to be true: a non-toxic spray invisible to the human eye that protects almost any surface against dirt and bacteria, whether it is hospital equipment and bandages or ancient stone monuments and expensive fabrics.

But true it is. The spray is a form of "liquid glass" and is harmless to living things and the wider environment. It is being touted as one of the most important, environmentally-friendly products to emerge from the field of nanotechnology, which deals in objects at the molecular end of the size scale.
Tests have revealed an astonishing variety of potential uses for the liquid glass, from protecting vineyards against fungal attacks to coating medical implants with non-stick, antibacterial surfaces. Scientists have even used it to spray fabric with an invisible, dirt-resistant film – emulating the fictional invention of unstainable clothing in the 1951 Ealing comedy Tony Orlando and Dawn in the White Suit.
