Scientists from the University of Electronic Science and Technology in China have developed a plasma that looks like a small light sword. It's used in medicine. They write about that topic Science of Warning.
A team of scientists at the University of Electronic Science and Technology in China has found a way to free the flow of microwave ions (plasmas) that can touch the surrounding surface. Their research was published in Zagreb Applied Physics Letters.
Unlike streams of charged particles, which can be produced only under vacuum or under special pressure, this plasma consists of small parts of stable gas, called plasma, which do not require special pressure.
For example, researchers can ionize the material with it, but can also help physicians sterilize their wounds, clean teeth, or even clotting themselves. "By developing low-plasma plasma jets, the use of plasma in biomedical areas would widen to skin treatment, sterilization and cancer treatment," says one scientist, Wenjie Fu.
The problem is, however, that the polarized tube of materials such as quartz was needed to stabilize the flow of these plasma nozzles. It would look like wrapping a light sword in a transparent plastic tube that would hold it inside, which was not the goal of a scientist. Instead, they made a coaxial cable, he writes Science of Warning.
The result is a directed plasma stream that can kill germs and help clotting blood and is cool enough to touch. Although premature for such technology, the latest scientific achievements could be an example of similar technology development in medicine.
