Within the infrastructure of Bilkent UNAM, Bilkent Holding and E-A Technology operating in Bilkent Cyberpark Technology Development Zone, has developed an “in vitro” virus diagnosis system that can be used to detect the new type of coronavirus. It is a fast and reliable virus detection method based on the presence or absence of the virus with optical methods. Diagnovir is a completely domestic invention with a new technological infrastructure.
The new nanotechnology-based diagnostic system can detect the COVID-19 virus within 10 seconds with a swab taken from the mouth. It is an optically based diagnostic and identification system that changes the color of the glow in the presence of the virus, thus detecting viruses with high selectivity. In this system, pathogens are detected within 10 seconds by dynamically receiving a fluorescent signal via a pathogen detection chip developed specifically for a biosensor device. After the sample taken from the patient, it is mixed with a special solution, dropped on the pathogen detection chip, and if there is a pathogen in the environment by the biosensor device, the presence of pathogens with high accuracy is detected by taking the fluorescent signal. Taking saliva samples from the mouth instead of taking swab samples from deep areas such as the oropharynx and nasopharynx will also make the use of the system preferable. Unlike the commonly used PCR tests, the system is not based on sample replication, but on detecting the presence or absence of the virus with advanced optical methods. In the system, optical and electronic modules that provide both precise virus detection and high selectivity in detection, as well as high-level biotechnology and material science knowledge are used. The system has shown 99% success in virus detection.
Diagnovir has a 99% reliability rate in only the first 10 seconds, eliminating the need for deep swabs used in PCR tests, providing accurate results even at the first time of the disease, being economical, working even with the presence of nano-level viruses, protecting healthcare teams and being able to be used in the detection of other pathogens in the future. It is a powerful alternative to the commonly used PCR tests in coronavirus diagnosis.
Test kit usage; Saliva taken from the person is used as a biological sample. A light swab is taken from any area in the oral cavity (eg inner cheek), the swab is dipped into the special solution and left for a short time, then the swab is thrown into the medical waste and approximately 30-50 µl is taken from the contaminated solution and transferred to a special disposable detection chip and the biosensor is placed in the device. The test gives a positive result if the solution is infected in the first 10 seconds. If it is negative, the test verifies itself, and the result is obtained in a maximum of 20 seconds.
