Scientists develop effective system of biomaterial delivery to laboratories

"[The method] used for  and obtaining

dry blood samples involves a few blood drops are applied to special cellulose carriers and then dried in air. It requires special 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 carriers due to the complex structure of cellulose and the presence of inconvertible adsorption of blood components, which greatly distorts the results of analysis," said Associate Professor Alexander Osipov, one of developers of the project.
That is why at the present time, medial syringes for gathering liquid samples of blood or serum for delivery to laboratories in special containers with specific 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,  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 chose the composition and form of the absorbent to ensure the blood was evenly distributed throughout the volume, and upon washing the analyzed  components, it almost completely passed into solution.
