The new nanotechnology-based diagnostic system can detect the COVID-19 virus in less than a minute with a swab taken from the mouth and just from the nasal vestibule. 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 in less than a minute by dynamically receiving a fluorescent signal via a pathogen detection chip developed specifically for a biosensor device. After samples 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 and mucosa samples from the nasal vestibule 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 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.
In less than a minute, Diagnovir has a 99% reliability rate, eliminating the need for deep swabs used in current 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 tests in coronavirus diagnosis.
Test kit usage; Saliva and mucosa sample 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) and from nostrils (Just the nasal vestibule), the swab is dipped into the special solution and rolled the swab around 10 seconds, then the swab is thrown into the medical waste and place 1 drop(approximately 20 µl) that taken from the contaminated solution and transferred to a special disposable detection chip and the biosensor is placed in the device. The test result in less than a minute.
