In the absence of real innovations in smartphones, I wouldn’t be surprised if a crazy manufacturer implemented a new method developed by researchers at the University of Washington – one that we can detect how many bacteria are in the mouth and skin.
The team led by Professor Ruikand Wang adapted the smartphone camera by adding black-light LEDs capable of highlighting various bacteria (after applying a specially created processing filter).
To make it easier to understand what these researchers have done, consider checking banknotes with a fluorescent light. And in this case we have a similar principle, some bacteria become radioactive when placed under a special light (black light). Basically, the image sensor in a smartphone can be “learn” to recognize these bacteria with the help of special LEDs.
Researchers at the University of Washington warn that their method cannot replace a medical diagnosis, but it can help prevent conditions such as gingivitis, acne, etc.
At first glance, it seems to me an almost useless find, but with well-thought-out marketing, it can attract many curious people.
