Invented in Turkey and patented by Nanopool, a German company, the spray-on liquid glass might become one of the most useful inventions in the field of nanotechnology. The product was tested at the Saarbrücken Institute for New Materials.
It is worth mentioning that the invention is transparent and non-poisonous. The liquid glass can protect any type of surface from damages caused by water, UV radiation, dirt, heat, and bacterial infections. Besides, it is flexible and breathable, which means that the liquid glass can be applied on plants and seeds as well. Researchers found that the spray greatly increases the resistance of plants to bacteria-caused diseases. The trials also showed that the sprayed seeds grew faster.
Depending on the type of surface that is to be covered, researchers can add water or ethanol to the spray. Scientists say that their latest invention has a long-lasting anti-bacterial effect. The spray produces a coating that is just 100nm thick. Trials by food processing plants in Germany have concluded that foods covered with the glass can store longer than those stored in normal condition.
According to Neil McClelland, UK project manager with Nanopool, due to its capabilities, the spray-on liquid glass can become one of the most useful inventions around the world, ending up being used by a lot of industries that will cover their products. At present, the invention is being used by a train company and a hotel chain in the UK, as well as a hamburger chain in Germany that are carrying out tests of the liquid glass for various uses.
The spray-on liquid glass was also tested in a Lancashire hospital, where it showed “very promising” results, being used to cover medical equipment and bandages. The invention could be also used on clothing, because it cannot be seen by the naked eye, thus clothes could become stain resistant. Due to its unique characteristics, the liquid glass can be used to cover bathrooms, sinks and many other surfaces in the home. According to the researchers, the spay-on glass can last for a year. It is expected to hit the DIY stores across Britain at a price of 5 pounds.

A. Water or ethanol must be added to the spray to produce the effect.
B. The coating of the spray-on liquid is thick.
C. The liquid glass can protect foods from bacteria.
D. The long-lasting anti-bacterial effect protects the liquid glass.
53. According to Neil McClelland, the spray-on liquid glass_________.
