Butterfingered portable device users worried about the fragility of their smartphones and other gear can rest easy now, thanks to nanotechnology.

Manila (the Philippines)-based startup Nanofixit has developed an innovative liquid screen protector that toughens display glass, adding a layer of shatter-proof protection heretofore unseen.

The company's patented formula consists of a unique mix of organic silicone and anti-bacterial titanium that penetrates and seals any electronic glass surface, imbuing it with near-diamond level (9H) hardness.

The screen protector works simply. For smartphones, one pea-sized drop is placed on the cell phone glass, rubbed diagonally and vertically with the finger for 30 seconds to cover the entire surface and front and back camera lenses. After 60 seconds the screen is wiped with a microfiber cloth provided until it shines.

Within a minute, the Nanofixit creates an invisible, ultra scratch-resistant layer that resists bubble formation, and also enhances the vividness of photos taken. The liquid is organic and odor-free.

The Nanofixit sports a pair of added benefits. It kills over 99% of E-coli bacteria and Staphylococcus bacteria - two of the most common, infection-causing bacteria among humans. The company also says it cuts cell phone radiation - an area of increased attention by health researchers - by some 90%.

The Nanofixit spent about two years in development; exports started from a year ago. One 1.5ml bottle of Nanofixit Titanium is enough for up to 10 devices, including smart phones, tablets, laptops, cameras, and watches, and has shelf life of about two years. The product works with 3D touch screens as well.

"Ideally, you wait for about a day for the screen protector to completely cure and seal before using, but devices can be used almost immediately after application," says Chief Creative Officer Michael Nielsen. "No smartphone screen is completely shatter-proof, of course. But with glass made six times stronger (with Nanofixit), the likelihood of disastrous accidents is dramatically reduced."

Nanofixit products were selected as winners of both an Analyst's Choice award and an innovative new product award for startups at Global Sources' annual October AsiaWorld Expo 2016 consumer electronics events held in Hong Kong.
