Wonderful Barry Fox on New Scientist describes a Motorola patent to kill germs on cell phones. After reading this, you will feel differently about putting your phone to your ear.

''The microphone and earpiece cavities in a cellphone make a warm and comfy breeding ground for bacteria. Squirting germicide into the holes can damage the electronics but now Motorola has a better way to kill bugs.

It has Motorola patented a phone containing an LED that radiates ultra-violet light with a wavelength of 250 nanometres which is particularly lethal to bacteria. Optical guides inside the phone body steer the UV light into the cavities. Sanitising only takes around 3 minutes, the company claims.
