Novosibirsk, March 15, 2016, 10:13 – REGNUM Siberian scientists have created a method for the rapid determination of hepatitis and other viruses, the official website of the Siberian Branch of the Russian Academy of Sciences “Science in Siberia”.
At the heart of the technology developed by the Institute of Semiconductor Physics. AV Rzhanova SB RAS, is a quartz resonator. The resonator is used as a sensor – sensitivity allows you to record even the smallest particles and single viruses. With this method it is possible to separate the bacteria of different types and to measure the strength of their bond with the surface.
According to the doctor of chemical sciences Fedor Dultseva , this method is based on the use of quartz crystal in the active mode, that allows you to measure the effect of breaking the bonds of the order of a dozen piconewton. With this technology determine particle size greater than 10 nanometers. To fix the finer fraction to the additional option of connecting pieces.
This development allows us to solve a variety of tasks that require the measurement of the particle binding force to the surface: recently it was used for the unwinding of the DNA double helix, and now the Novosibirsk scientists are ready to use a new way to search for and study of hepatitis. They argue that the effectiveness and results will not be worse than that of the most expensive methods.
«Using our development, we can not simply determine whether there is a sample of hepatitis, but also to study the structure of the particles. It turned out that this virus is a structure consisting of loosely connected parts. When he clings to the surface, and then comes off from it completely, and begins to fall apart into pieces. This allowed us to see our technology “, – said Fedor Dultsev.
Currently, the Siberian scientists, together with MBA Technology company developing portable device with which it would be possible to conduct a rapid analysis and determine if the virus is in the sample being studied. As noted by Siberian scientists, among the advantages of the future product – a simple hardware and simple preparation of samples for analysis.
Production of an experimental batch of devices is possible as early as next year. At the same time it becomes clear how affordable will it cost. First, the instrument to be used in laboratories, but it is possible that then it goes in the ordinary clinics and hospitals.
