Mikhail Rayev graduated from the Faculty of Biology and Chemistry, Perm State Pedagogical Institute, in 1981. He earned his Ph.D. in Biological Sciences from the Institute of Immunology, Ministry of Healthcare and Social Development of the Russian Federation (Moscow), in 1995, and obtained the degree of Doctor of Biological Sciences at the All-Russian Center for Emergency and Radiation Medicine, named after A.M. Nikiforov, under the Ministry of Emergency Situations of Russia in 2008. His current research focuses on the development of advanced non-instrumental diagnostic methods based on original technologies for reliable surface functionalization of nanoscale particles. He is dedicated to creating reagents for a variety of analytical and diagnostic test systems without the need for specialised hardware, which can be applied to hospital and community testing, ambulance emergency services, emergency response teams, military units, epidemic management, field operations, and veterinary practice. His research also covers the development of innovative approaches and technologies for the isolation of biological macromolecules and bioactive compounds from different sources, as well as the structural modification of biomolecules.
