Siberian scientists have created a method for the rapid determination of hepatitis and other viruses – Infopro54.ru

At the heart of the technology developed by the Institute of Semiconductor Physics. AV Rzhanova SB RAS, is a quartz resonator, which is used as a sensor -. Its sensitivity allows to register the smallest particles and even a single virus, said the publication “Science in Siberia»

With the help of the method of Novosibirsk scientists can separate the bacteria of various types and to measure the strength of their connection to the surface – in the moment when the plane of the detached particles, experts allocate a special acoustic signal. All this helps to detect single viruses and phages.

As the doctor of chemical sciences Fedor Dultsev, the method is based on the use of quartz crystal in an active fashion. With this technology determine particle size greater than 10 nanometers. 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 is now ready to use IPP in a new way to search for and study of hepatitis. According to the authors, the effectiveness and the results will not be worse than that of the most expensive methods

-. With our development, we can not simply determine whether there is a sample of hepatitis, but has and study the structure of the particles, – says Fedor Dultsev. – 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.

Now, scientists in conjunction with the 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. According to Fyodor Dultseva, 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 already possible in the 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
