American Scientists Have Created A Detector For The Instant Detection Of COVID-19 In Humans

Researchers from the George Washington University in the Metropolitan District of Columbia have created a miniature device that allows almost instantly detect the presence of a human coronavirus, or traces of antibodies formed in the body in response to this pathogen if the patient has already had this infection. It is noteworthy that the detector is based on the method of color spectroscopy, and the patient can get the test results on a special application to the phone. The researchers' work is available on the specialized portal MedicalXpress.

The detector, consisting of conductors as thick as a strand of human hair and covered with a thin layer of gold, is able to react to substances in the gaseous state and signal them by changing the color of the indicator.

In turn, artificial intelligence, analyzing the reaction of the detector, is able to determine what kind of substance is in the human blood.

"During a pandemic of this kind, rapid tests are very important," notes the author of the development, Professor of computer engineering at George Washington University Mona Zaglul. "Our employees were able to calibrate the device in such a way as to detect the presence of coronavirus in the blood, in the same way as the antibodies in the bloodstream formed in patients who had been ill with OVID-19."

Technically, it looks quite simple, the scientist explained. To do this, the detector must be treated with a solution containing proteins that are specifically associated with the coronavirus. If a person is infected with SARS CoV-2, the virus, coming into contact with the surface of the detector, is able to change the color of the indicator. After capturing the optical metamorphosis on a mobile phone, the patient immediately receives an answer, whether he is a carrier of the virus or not.

"This device is especially necessary now when the success of treatment and - most importantly - the ability to prevent the spread of a dangerous infection depends on how quickly doctors can detect infected people," explains co-author of the invention, Dr. Jeanne Jordan from the school of public health at the Milken Institute in Santa Monica (California). "We must equip medical practitioners and social services with equipment that can help in the daily work of doctors."

Zaglul, in turn, is confident that with the help of artificial intelligence and the developed detector, it will be possible to process extensive databases on the number and composition of detected patients and carriers of coronavirus. "Specialists and patients will be able to upload information directly to the cloud," the Professor says.
