In developing countries, access to trained doctors and medical laboratories is very difficult, so it was necessary to create accurate, and above all, compact tools for the detection of various diseases. Researchers at Florida Atlantic University have been able to develop a pocket-sized smartphone-based virus detector.
Smartphones have long since ceased to serve as a communication tool and are increasingly becoming a medical accessory. There are already good starters to help with their blood sugar levels, as well as eye tests. Thanks to the efforts of Florida Atlantic University scientists, these popular devices have now turned into pocket-sized virus detection tests.
The team of researchers has been able to create special tests that, when applied to the patient’s blood, can be tested for the presence of sticks or even HIV. The test consists of two parts, namely a thin strip, over which a blood sample is applied, and an application for a smartphone using a built-in camera. Each strip identifies another type of disease, and if the virus or bacteria are found in the sample, the nanoparticles will color the blood.
If you do not have a medical lab at hand, then you will be able to send it to the professionals who will do the final analysis to determine if the patient is indeed infected.
According to the inventors of the test, the technology developed by them can in future be adapted to detect more diseases as well as pathogens found in food and water. For more information about the research, see the latest issue of Scientific Report.
