Denpa News Saliva analysis for coronavirus is carried out using optical methods using nanotechnology, Bilkent University said
The Diagnosis device is capable of diagnosing infection with the SARS-CoV-2 coronavirus in ten seconds by analyzing saliva with a 99% probability. This is stated in the message of the press service of the private Bilkent University in Ankara, published on the institution’s website.
“Unlike the widely used PCR tests, the system is not based on replicating samples, but on detecting the presence or absence of a virus using advanced optical techniques. The system uses optical and electronic modules that provide both accurate detection of viruses and high selectivity of detection. We believe that this system will be widely used in our country and in the world as a fast and reliable method for detecting viruses, ”the message says.
The technology for detecting the virus has been developed for seven months and is capable of working in the future not only with SARS-CoV-2 but also with other pathogens.
The detection system is based on optical methods, and a special pathogen detection chip has been developed for it. The sample taken from the patient is mixed with a special solution, and the mixture is dripped onto the pathogen detection chip. If a virus is detected in it using a biosensor device, the color of the fluorescent glow changes.
In February 2020, even before the pandemic was announced, researchers from the Hong Kong University of Science and Technology (HKUST) said they had invented a portable coronavirus rapid diagnostic device. “Thanks to the latest microfluidic chip technology, the device can detect a virus in just 40 minutes,” they said at the time.
Specialists of the Krasnogorsk plant named after S.A. Zvereva (KMZ, part of the state corporation) in August 2020 announced Shvabe holding of the Rostec that they had developed a device for detecting viruses in the air, including COVID-19. The device is called “Detector-BIO”, the analysis of an air sample with its help takes from 10 to 30 minutes, depending on the concentration of pathogens and other factors.
