MOSCOW, May 19, 2017 /PRNewswire/ --

Materials scientists from NUST MISIS , together with colleagues from the Department of Chemistry at Lomonosov Moscow State University, have developed a cheap an d qualitative method of delivering blood samples and other bi ological fluids at any distance to be analyzed in laboratories. The developed method is similar to the technology of obtaining dry blood spots, which has already proven useful in neonatal screening. The new technology in this field has wide-ranging possibilities, and in the near future may displace traditional methods of sample collectio n to become the new method of screening population s for communicable diseases (HIV, hepatitis, tuberculosis, etc.) . These possibilities are now being discussed in professional environment s .

" [The method] used for neonatal screening and obtaining dry blood samples, when a few blood drops are applied to special cellulose carriers and then dried in air, requires specia l cards not produced in Russia , as well as expensive specialized equipment for obtaining samples of biomaterial for further analysis. And this technology doesn't even exist in every major city. Additionally, the difficulty of using such carriers for quantitative analysis of animal and human blood is caused by irregularity of its diffusion on carrier s due to the complex structure of cellulose and the presence of inconvertible ad sorption of blood components, which greatly disto rts the results of analysis," said Associate ProfessorAlexander Osipov, one of developers of the project,aCandidate of Chemical Sciences,and asenior research assistant at NUST MISIS Department of Functional Nanosystems.

That is why at the present time, special medial syringes-vials for gathering liquid samples of blood or serum and delivered to laboratories for analysis in special containers with special temperature conditions (often frozen) are used in medical and veterinary diagnosis. The whole process is quite expensive and inconvenient. In addition, if a violation of temperature or time conditions occurs during the delivery or storage, blood samples lose their properties, possibly leading to incorrect results.

This problem was solved by replacing the cellulose with specially-prepared porous inorganic material containing nanoparticles of metals. Scientists managed to choose the composition and form oftheabsorbent so the blood was evenly distributed throughout the volume, andupon washing the analyzed blood componentsitalmost completely passed into solution.

Modified samples dry about 2 times faster, which critically speeds up sample preparation process. To transport to a laboratory, the card is put in an envelope and sent by mail without need of special transport, which leads to significant financial savings. For example, in past events of an emergency epidemiological situation - like the outbreak of the Siberian plague in Yamal in 2016 - the cost of express delivery of a batch of biomaterials to a Moscow lab amounted to several million rubles.

The cost of the card itself in manual small-scale wholesale production is five times lower than industrial imported cellulose: 40 Rubles against 180 Rubles. When considering large-scale production the price will be even lower.

Now the creators of the new patented technology of sample preparation have decided to focus on veterinary diagnosis, because in animal breeding and farming there is a need to conduct hundreds of thousands of tests, but there are no conditions for these tests on farms located in remote areas.

The Federal Center for Animal Health (FGBI «ARRIAH») has become the main partner of the practical approbation of the proposed technology (Russia, Vladimir). Now scientists are collaborating with some of Russia`s largest poultry and animal farms, which determines the level of bird immunity, vaccinations, the presence of the FMD virus, rabies, leukemia, and other particularly dangerous infections animals may have. After the completion of testing and certification procedures, it will be possible to start the serial production of a pilot series of membrane carriers of the new model for sample selection. According to preliminary estimates, all necessary documents will be ready by the end of 2017.

There are now negotiations being conducted with the leading Russian diagnostic laboratories for use of the new technology in medical diagnostics, including screenings for communicable diseases such as hepatitis, HIV, and others. In addition, several large companies from Southeast Asia have also expressed interest in using the new system both in veterinary and medical diagnostics.

The system was developed through the framework of the Federal Target Program «Research and developments in priority areas of advancement of the Russian scientific and technological complex for 2014-2020» (Agreement № 14.578.21.0010) with the support of the Russian Ministry of Science and Education.
