Can diagnose the disease by spitting on the smartphone

Two South Korean scientists, Hyun Gyu Park, and Byoung Yeon Won, believe that the touch-screen smartphone will soon be used as a diagnostic tool benhcho users.
As such, anyone who wants to self-diagnosis will need to give a little saliva on the touch screen and a special application will make the diagnosis.

If research scientists have progressed further in the near future, the people spit on their smartphone to diagnose becomes very ordinary. And the patients treated at home can track the status of their patients, saving an unnecessary trip to the hospital.
As explained by the New Scientist, working applications based on the ability to identify very small differences between different types of saliva, depending on the status of the virus in saliva, via touch screen . Park said: "Since the touch screen can identify very small differences in capacitance technology, we thought that we could serve for the detection of biological signals."
The iPhone has a screen used for research, and it was really capable of detecting bacteria, even the perception of the bacterial concentration in tiny sample of saliva on the screen . But both scientists acknowledged that much remains to be done because current technology can not identify the causative agent, which they thought possible. And one more thing that not everyone is willing to dirty his phone. In this regard, Park is planning to develop a dedicated film panels can be stuck on the touch screen.
