Plastic micro granules help in the treatment of burns
A major problem in the fight against harmful microbes is evolution, which generates strains of bacteria resistant to antibiotics and other medicines. Mankind must admit that it can not support the pace of this “race ahead of the curve,” scientists at Birmingham University believe. And they offer alternative methods.
The team of Dr. Paul Roberts used microscopic granules of polystyrene as a “bait” for bacteria. They covered the plastic with a protein called a “polyvalent adhesive molecule-7”. Bacteria use it as a marker to communicate with the cells they attack – instead, scientists forced them to cling to plastic granules. Then it remains only to remove the plastic from the wound along with the adherent pests.
Roberts’ mathematical models have shown that nothing can be cured in this way, but plastic baits-granules are convenient for intermediate treatment of wounds. For example, burns and cuts to remove from the damaged tissue site pathogens. Technically, this is a kind of sanitation, removal of necrotic tissue and by-products for cleaning wounds.
Another way to use plastic bait – as an addition to traditional antibiotics. If you first remove a certain number of microorganisms from the target zone, the active substances will be easier to destroy the remaining ones. However, so far all this is only a theory, and the first practical experiments have yet to be carried out.
