COVID-19 is still one of the biggest problems humanity is dealing with. Scientists do not have a clear idea of how long this situation will last. They say he may or may not be with us for years. If so, will the PCR test hold up?
It won’t last, of course, because it’s expensive. With this in mind, University of California Santa Barbara scientists are developing a test method to find out if you have COVID-19 using just your smartphones and simple lab kits. Moreover, it was effective not only for COVID-19, but also for the flu.
You can test on your phone for only 7 dollars
If you’re wondering, “How can using laboratory kits and smartphones be at the same level as PCR testing, which has a very affordable price tag by US standards ($7)?”
The method works like this: The user downloads the application called ‘Bacticount’ developed by scientists. It then turns the smartphone’s front camera into a portable heater. Finally, a sample of oral saliva is placed in the $7 test kit and placed on the surface of the portable heater.
This test contains a reactive solution that will make the infected RNA more noticeable on your phone’s camera. If the screen turns bright red when the application is run, the result is positive. The app can also estimate the amount of virus based on how fast the color reaction occurs.
Do you think there will be a standard method that we can test such infectious diseases from the phone in the future? Please do not forget to express your thoughts in the comments.
