A group of Russian scientists has developed a prototype of a hardware-software complex that allows to determine for a short time the presence and concentration of a virus in human biological material. TASS.
The peculiarity of the device lies in the fact that different locally produced biosensor sensors can be integrated into it.
“The working principle of the developed device is based on the following. A special biological material is applied to a sensitive substrate, on which an electric current is generated when a virus enters. This current is recorded by the developed prototype, analyzed and a conclusion is drawn about the presence and concentration of the virus on the substrate. “The developed system allows you to change the sensitivity of the device and is a universal tool for diagnosing viruses of various types and, as a result, currents of various sizes,” said project manager Irina Dolgikh, head of the technology development program. Novosibirsk State Technical University (NSTU) Transfer Center.
The prototype was created by a team from the Faculty of Radio Engineering and Electronics of Novosibirsk State Technical University and is part of an interdisciplinary project involving employees of the Institute of Semiconductor Physics of the Siberian Branch of the Russian Academy of Sciences, Vector Virology Center, Vostok Novosibirsk Semiconductor Plant and All-Russian Physical and Technical and Radio Engineering Measurements Research Institute. Now scientists have developed a system for receiving nanoampere signals from biosensor sensors, as well as a user-friendly data processing process and sensitivity settings for different types of biomaterials.
Scientists hope that in the coming years, such a device will be available to anyone who wants to check for the presence or absence of a virus in the body. In addition, the development of such a device opens the possibility of creating a set of hardware and software systems for the laboratory diagnostic market, as well as devices that can be installed at airports, railway stations, schools, shopping centers and public facilities. entertainment and business centers and others. Development is carried out in the framework of the strategic project “New engineering solutions for biomedicine and artificial intelligence” in the development program “Priority-2030”. According to the results of the selection for the Priority 2030 program, NSTU NETI entered the second group on the path “Regional and (or) sectoral leadership”.
