The future of medical diagnoses may lie in simply spitting on your phone

The future of medical diagnoses may lie in simply spitting on your phone
When we aren’t feeling well, many of us scurry to the Internet to use online symptom checkers in an attempt to self-diagnose our ailments. While this is more convenient than running to the doctor for every cough and sniffle, many people leave the web fearing they have every possible disease related to their symptoms. Hyun Gyu Park and Yeon Won at the Korea Advanced Institute for Science and Technology think touchscreens can replace lab work, resulting in people being able to run self-diagnostic test right from their phone.

Today’s touchscreens have a much higher sensitivity than what is actually required for most smartphone activities. Park said, “Since these touchscreens can detect very small capacitance changes we thought they could serve as highly sensitive detection platforms for disease biomarkers.

In order to test their theory, Park and Won applied three solutions that contained differing concentrations of DNA from the bacteria that causes chlamydia to a multi-touch display the size of an iPhone screen. What they found was, the touch-sensing electrodes on the screen were able to distinguish between the electric charges of each sample even though they only used a very small amount. While it is not able to identify individual pathogens, they view this test as a successful first step toward achieving their goal.

The biggest hurdle to making this technology a reality is that the software used to eliminate false-touch signals, commonly caused by sweat or moisture, would need to be modified. Harpal Minhas, editor of the journal Lab On A Chip, admitted, “Any changes to current production-line touchscreens would need to demonstrate huge financial benefits before they are implemented."

This isn’t something we expect to see very soon, but it is a fascinating look into the medical possibilities of mobile technology. For those of you that like the idea of quick, private self-diagnoses, but not the idea of spitting or putting other ‘samples’ on your phone, Park also says that he intends to develop a film that can be adhered to the touchscreen for testing because “Nobody wants direct application of bio-samples onto their phone.” We couldn’t agree more.

Better have insurance for your phone.

right, but at least you won't have to worry about someone asking to use your gross germy phone.

Yea, I don't think I'd want to spit on my phone and then not have it work later. :\ But hopefully they'd create some sort of protectant with the cool disease detector.

God forbid you do have something and someone needs to use your phone right after for an emergency... Now where are the comments about how people would love to spit on an iPhone and/or Android? lol

I wonder why you can "taste" that in the future. That gives me a bad image of people licking others peoples phones or something. The furthest I can ever taste the future is if I have cake in the oven.

Phones already smell. You do not have to wait for the future... just put the microphone end right up to your nose, and take a big, deep whiff. If you have a non-touchscreen phone, just try the keypad... it will smell even more thanks to all the finger-cheese! LOL!

The next thing you know, they will have an app that analyses urine samples. Just pee on the phone for things like pregnancy tests. Oh, remind me not to borrow anyone else's touch screen phone ever.

It's been proven that most phones are dirtier than a toilet seat, so why trip? Atleast your enzymes will break some of them down, plus there are products called "disinfectants".
