According to a new research by the scientists, coating for smudge-resistant touchscreens will be bacteria and fungi free. This can be achieved via titanium dioxide paints. A team of engineers is working for titanium dioxide coatings for glass. If they successful, the costing might go for touch-screen devices in near future and you don’t need to clean your touch-screen smartphones.

Titanium dioxide has the property to destroy microbes and the stubborn layer of slime. Under the Sun-light titanium dioxide molecules produce free radicals and these radicals then damage their DNAas these radicals penetrate the cell walls of bacteria and fungi. The coating will need 1 hour of Sun-light to work. At Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Germany a test is already carried out.

Michael Vergöhl, who leads sun-activated surfaces research states, “If you apply a thin coating of titanium dioxide to a glass surface such as a smartphone screen, the skin oils and fingerprints gradually disappear from the display by themselves.”
