Russian scientists have developed a new anti-scarry coating by using modified carbon which is now used in applied medicine. The discovery was made by Professor Valery Levchenko, a leading expert in nanotechnology at Moscow State University. This is an absolutely biocompatible polymer that has no analogue in the world.

Russian scientists have developed a new anti-scarry coating by using modified carbon which is now used in applied medicine. The discovery was made by Professor Valery Levchenko, a leading expert in nanotechnology at Moscow State University. This is an absolutely biocompatible polymer that has no analogue in the world. It is laid on a wound received during an accident or a fire, and it heals without leaving a scar owing to its properties. The new coating improves blood circulation during the healing process and promotes life-sustaining activity, and consequently, prevents formation of scars. The material is known as multifunctional carbon polymer and is used to make plasters and dressing materials and various kinds of medical equipment.

Experts at the Institute of Molecular Biology of the Russian Academy of Sciences have developed a new technology to make biochips that make diagnosis of social illnesses. Similar to electronic microchips that process a large amount of digital information, bio-chips are designed for reading molecules and processing a large amount of biological information. This is a plate that contains hundreds of elements each of which is an individual micro–test-tube. It can be used to get clinical analyses in many parameters. For one, a drop of blood is sufficient to make a blood test that will show which virus has caused the infection or epidemic or give a picture of dozens or hundreds of various factors.

At present, biochips are often used to reveal genetic compliance with various illnesses, including cancer. The experts have also developed a biochip for the identification of personality for judicial and medical expertise. This method does not need expensive equipment and highly qualified personnel. The new development is protected by 30 international patents. The institute has already set up a facility to produce over million chips a year. 

A group of Russian biologists, physicists, material engineers and mathematics have worked together for 12 years to develop a technology and laser equipment to correct deformed or injured cartilages. The cartilage is a specific tissue in living beings and it has no blood vessels or nerves, but at the same time it possesses the memory of its form. For one, if we bend an ear, which is a cartilage covered with a skin, it will return to its previous form when we release the grip hand.

However, experts insist that, it is possible to change the form of cartilage by heating it for a short period while using a laser. This will not damage tissues, but relives tension. Degenerative illnesses of spinal bones are now being treated using laser that restores cartilages between the discs. This method helps to correct a distorted nasal septum. In fact, 20 percent of the world population suffers from this disease.
