U.S. nanotechnology continue to develop this area, and this time they have created nanohub, which can absorb trapped in the body poisons insects and snakes, as well as bacteria. They already have successfully tested his invention on mice, while protecting them from the lethal dose of Staphylococcus, reported in the journal Nature Nanotechnology.
According to Lantana Zhang from the University of California in San Diego, they managed to create a fundamentally new method of removing toxic substances from the blood. Their development is not the antidote to specific kinds of poison, and she is, in fact, the platform, which is able to neutralize most of the toxins trapped in the body from a variety of sources. In addition, it is able to deal with the discharge of Staphylococcus and other bacteria, which today have become resistant to antibiotics. Nanoparticles avoid the attention of the immune system and destroyed them thanks to a specially designed system of "camouflage".
According to scientists, "net" nanoparticles cannot exist for a long time in the bloodstream, as the immune system begins to recognize them and deal with them. To do this, scientists made a special protection for the nanoparticles with the help of red blood cells. In addition to the protective function, this "camouflage" improves the ability to absorb molecules of toxins, which are aimed at the destruction of red blood cells.
Experiment on mice was successful, as the nanoparticles remained in the body of rodents more than 40 hours, having had time to absorb most of the toxins of Staphylococcus aureus. After "camouflage" nanoparticles was destroyed, the cells of the immune system brought nanoparticles in the liver, where the polymer base and all the toxins have been successfully destroyed. Currently, scientists plan to begin clinical trials of its development.
