Scientists from the Zelenograd Nanotechnology Center Igor Kosourikhin, Denis Levin and Roman Morozov (from right to left) demonstrate a solution for the formation of the main layer of the regenerating miracle sponge
The Vecherka correspondent visited the Zelenograd Nanotechnology Center, whose engineers invented an unusual sponge for regenerating damaged tissues.
At the Zelenograd Nanotechnology Center, work on projects for the future is in full swing. Many PhDs are barely 25 years old. The results are impressive. When they promise to show some special "framework for tissue regeneration", the buzzword "exoskeleton" comes to mind.
Scientists just brush it off, because the sample resembles a tiny shortbread cookie.
- With him, no wounds are terrible, - proudly declares Roman Morozov, head of the medical device development department. - Now, after all, doctors use only European sponges for operations, and they are much less effective.
The multi-layer design of the wound swab resembles a napoleon cake. Each of the layers is unique and consists of collagen, chitosan, and albumin. In addition to the fact that the blood stops flowing, the wound heals faster.
When developing, it was necessary to take into account a number of nuances. For example, the fact that blood has a very sticky structure.

When a doctor applies tweezers with a common European sponge, blood adheres, further damaging the tissue. In the case of a puff frame, this is impossible - the blood refuses to reach for the material.
- We kind of deceived the body, - smiles Roman Morozov. - When a doctor applies such a sponge to a wound, blood cells begin to work hard to make it heal faster. It's all about the unique composition.
Clinical trials in rats have shown positive results. A new stage of research lies ahead.

DIRECT SPEECH
Vladimir Khoroshev, surgeon:
- Such a frame is usually called a house for cells. Scientists all over the world have been conducting research in this direction for many years. Of course, the development of the guys from Zelenograd is of colossal value. Surgeons are in great need of an improved framework.
Ramil Rakhmatullin, research doctor:
- In this case, it is valuable that the guys are developing an analogue of the European sponge. We, in Russia, should have our own, much more effective medical innovations. And doctors will thank the engineers more than once for the framework for tissue regeneration. In some micro-operations, blood flows so that it is impossible to work.
Konstantin Agladze, Head of the Laboratory of Biophysics of Excitable Systems at the Moscow Institute of Physics and Technology, Candidate of Physical and Mathematical Sciences:
- Tissue engineering is a promising direction in regenerative medicine. We are talking about serious surgical interventions. In other words, the ambulance doctor will not be able to use them yet. We can say that these are developments of the future.
