American scientists from the University of North Carolina has developed nanosystem, which after the introduction into the human body releases insulin when the glucose level in the blood is increased.
Experiments in rodents have established that the effect of a single injection, which contains nanoparticles with insulin, enough for ten days. Thus, if such a method of treatment of diabetes of the 1st type will be put into practice, it will enable diabetics not be measured several times a day the level of glucose in the blood. In addition, diabetics will no longer require multiple daily insulin injections because of nanosystem itself will control the level of sugar in the blood and release the amount of insulin, which the body needs.
The new system is similar to the function of the pancreas, which, as you know, diabetes is not working efficiently. It consists of nanoparticles, which is insulin. It is surrounded by a material which consists of the enzyme glucose oxidase and dextran. When the glucose level rises, the enzyme converts it to gluconic acid, dissolving the dextran and releasing insulin. Kernel coated with a special material with a porous surface, which has a different polarity. This allows the nanoparticles is not sprayed on the body and stick together. At the moment the developers know-how to discuss the issue of conducting clinical trials in humans.
