Doorknobs. Keyboards. Mobile electronics of all kinds. I'll take "things that are always covered in germs and crap, and which I really prefer not to think about" for $400, Alex. Yes, all the things you touch every day have a nasty habit of leaving gunk on your touchscreen phone - it's kind of part and parcel of the whole "touch" thing. But Corning wants to make you feel a little less gross when you think about that with its new version of the ubiquitous Gorilla Glass.

They call it Antimicrobial Corning(R) Gorilla(R) Glass (really?), and though it was announced way back in January of last year, the recently-revealed ZTE Axon is the first phone to actually use the feature. According to Corning, the antimicrobial layer on the glass will last for the lifetime of the phone, on top of the patented durability and scratch resistance. The glass is registered with the EPA.

Of course, "antimicrobial" isn't worth as much as you think - while the surface will technically kill or inhibit bacteria, fungi, protozoans, and other itty bitty beasties, the applications for technology like that aren't all that useful outside of the medical or food prep fields. Your skin and immune system are better at neutralizing potentially dangerous microbes than any passive surface, and even Corning's press release says that the company "makes no direct or implied claims to protecting users or providing other health benefits."
