Materials scientists from NUST MISIS, together with colleagues from the Department of Chemistry at Lomonosov Moscow State University, have developed a cheap and qualitative method of delivering blood samples and other biological fluids over 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 collection to become the new method of screening populations for communicable diseases (HIV, hepatitis, tuberculosis, etc.). These possibilities are now being discussed in professional environments.
