Nanotech coating for wound healing


14/07/2012

Experiments on mice conducted by researchers from the University of Wisconsin-Madison, have proved that for rapid healing of wounds and the prevention of infection can be used ultra-thin layer of a polymer containing impregnated surgical germicide.

This technology was developed in the laboratory of Professor H. Abbott. U.S. scientists have created a polymer film that contains chlorhexidine, and attached it to the already sold in the market bandage to cover the wound. Sometimes these are called faux leather armbands, as they contain biological molecules that trigger rapid healing. Therefore, such materials are the primary means for treatment of chronic ulcers and burns. The problem is that often block the infection process of wound healing. The number of such cases is 20%, with effect from the use of "artificial skin" turns out to be zero.

U.S. scientists have found a way to cope with the occurrence of unwanted infections. Specialists of Wisconsin-Madison offered routed between "artificial skin" and wound gauze bandage, pre-impregnated with chlorhexidine. Unfortunately, it appears that high concentrations of antibiotic young skin cells die as a result of healing is slowed down only. But still it is necessary to periodically change the gauze bandage, that is, will have to expose the wound.

Through the use of nanotechnological approach scientists have a much lower concentration of chlorhexidine, which is released gradually polymer film. The effectiveness of the new approach in blocking infection and stimulate healing was confirmed in experiments on mice. In particular, the results of experiments confirmed that the use of new nanotechnology material for the first three days of the use of "artificial skin", the number of bacterial colonies can be reduced by 99.9%. And if you are dealing with chronic ulcers or burns, the prevention of infection in the first days after application to a wound "artificial skin", gives 90 percent chance of a successful and rapid healing of wounds.
