In developing countries, local disasters and disaster clean water and sterile instruments are vital, particularly in obstetrics, surgery, treatment of injuries and wounds.But it is in the water and sterile instruments, local physicians lack.
Enough has long been known that the ionized plasma contributes to the destruction of microorganisms in the water.However, recently it has been shown that by using as the plasma can be sterilized instruments and even accelerate the healing process.Given that the device forming the plasma is inexpensive, such a thing could be the salvation for developing countries.
By Philip Denny opinion, director of the research center of the University of Berkeley (USA), low-temperature plasma as a disinfectant is indeed a very promising innovation that can significantly improve the quality of life in affected countries and regions.
study by researchers from Berkeley, published in the November issue of the Journal of Physics D: Applied Physics, showed that after several hours of disinfecting water by the plasma destroyed 100% coliform.In the seven days the water remains clean of bacteria 99.9%.
Considering that mutant strains of E. coli (infection occurs through the meat, vegetables, cheese) can lead to the development of strong intestinal disorders and even death, the elimination of this bacteria is an important character.
In another study, the same authors have shown that plasma is able to destroy the dangerous protein and lipid molecules, the so-called prions causing mad cow disease.These data are particularly interesting in that other sterilization methods do not lead to the destruction of prions.
In 2009, researchers from the Max Planck Institute (Germany) have made the device, which is capable of using plasma disinfecting human skin within seconds, while consuming even drug-resistant bacteria.Thus, there are a promising new methods of using the plasma every year.
new study which substantiated the mechanism of action of the plasma was carried out in 2011.The fact that the plasma in contact with water becomes acidic latter strongly.As a result, water accumulates in the original cocktail of chemically active substances, ions, radicals.
In particular, they found high levels of hydrogen peroxide, nitrates and nitrites, are known to have a pronounced antimicrobial action.For example, nitrates and nitrites are widely used in developed countries to prevent spoiling of meat products.
As noted above, water, disinfected plasma for a long time maintains its properties, although the level of peroxide and nitrite in it decreases.Long-term antimicrobial effect due to the presence of nitrates.
Regarding the use of plasma in medicine, the history of its application starts with the XIX century.In those days, the plasma used to produce ozone, which is used for water purification, as well as for the production of hydrogen peroxide to sterilize surgical instruments.Recently, special plasma devices use for surgical operations.
When studying the properties of plasma, it was found that there is a "hot" plasma in which the ambient temperature increases and low-temperature plasma, at which also a large amount of oxygen radicals, nitrates and nitrites, but without significant heating.
Thus, the idea of the possibility of using low-temperature plasma for decontamination of the skin.Oxygen radicals and nitrates will penetrate into the deep layers of the dermis and destroy pathogenic flora.
Prospects of huge plasma, but the researchers themselves point to the need for further experimentation and development.
