Technology of modification of physical and chemical properties of micro and nanodimensional bioobjects in noble-gas plasma for applications in the sphere of medicine and pharmacology

Project is aimed at creation of modification of physical properties medical product with condition of preservation of material’s chemical structure, which will help to increase effectiveness of existing medicaments

Aim of the project:

  • Getting of thoroughly modified biopolymers (excipients of medicine, medical bases)
  • Creation of the way of medical substance’s effective surface area increase for increase of absorption of active substances

Technology is based on the use of self-organizing well-ordered plasma-dusty structures in low-temperature plasma of reactionless gas. Such distribution of treated substance proves its effectiveness during creation of thoroughly surface-structured components.

Fields of application:


  • Microcapsulation
  • Surface-modified preparations in the form of dust
  • Modification of the surface of biopolymeric bases of medical preparations
  • Bioexcipients for preparations with low solubility in water


  • Markers with modified surface
  • Micro- and nanoparticles with special structure of surface
