Sensitivity detection of HIV with the naked eye

British scientists have recently developed a super-sensitive sensor that allows detection of many diseases and viruses at the earliest.

The research, published in the journal Nature Nanotechnology, shows that visual sensing technology developed by scientists at Imperial College London can detect many serious diseases including prostate cancer and HIV virus in the early stages through typical biomarkers.

According to the scientists, each biomarker expresses a certain disease. With a sensitivity of up to 10 times the current standard, the sensor will help doctors accurately detect the type of disease a person is suffering from by coloring. For example, if you identify a biomarker called P24 in your blood, it means the person is carrying a deadly virus - HIV or a PSA antigen, an early sign of a cancer of the gland. Immediate, immediate reaction occurs, causing the sensor to change to a specific green corresponding to that disease. The opposite will be red. Both reactions can be easily seen with the naked eye.

Researchers say the sensors they develop will bring multiple benefits, such as 10 times cheaper than traditional methods, simple use and the ability to cure patients in countries. where modern medical equipment is scarce.
