En artikel på Physorg.com beskriver en ny produkt, flytande glas, som lovar att ”revolutionera nästan allting”. Inom kort ska flytande glas säljas som spray för ca 5 GBP (60 kr) flaskan. Produkten kan användas på bord, ugnar, växter, duschutrymmen osv och gör starkare rengöringsmedel mer eller mindre obsoleta. Tester av livsmedelsföretag i Tyskland har visat att ytor behandlade med sprayen som sköljs med varmt vatten är mer sterila än obehandlade ytor som tvättas med starkt blekmedel.
Liquid glass was invented in Turkey and the patent is held by Nanopool, a family-owned German company. Research on the product was carried out at the Saarbrücken Institute for New Materials. Nanopool is already in negotiations in the UK with a number of companies and with the National Health Service, with a view to its widespread adoption.
The liquid glass spray produces a water-resistant coating only around 100 nanometers (15-30 molecules) thick. On this nanoscale the glass is highly flexible and breathable. The coating is environmentally harmless and non-toxic, and easy to clean using only water or a simple wipe with a damp cloth. It repels bacteria, water and dirt, and resists heat, UV light and even acids. UK project manager with Nanopool, Neil McClelland, said soon almost every product you purchase will be coated with liquid glass.
Food processing companies in Germany have already carried out trials of the spray, and found sterile surfaces that usually needed to be cleaned with strong bleach to keep them sterile needed only a hot water rinse if they were coated with liquid glass. The levels of sterility were higher for the glass-coated surfaces, and the surfaces remained sterile for months.
