The new study found that: the spread of short wave ultraviolet light or can slow down the flu

It is reported that the hospital and laboratory often uses ultraviolet light to kill bacteria, but this method has one major disadvantage, namely to cause harm to humans. Therefore, only in the UV operation room and empty laboratory hood and other local sterilization.

At present, the researchers found that shorter wavelength UV sterilization may have no harm to human body, and according to the theory, the development of a new tool, can be in school, crowded airplanes, food processing plants, even the operation room and laboratory use, thus slowing the spread of disease.

The UV damage will molecular genetic material and proteins of bacteria together to achieve sterilization. Which is the most commonly used 254 nm light wavelength, including shorter wavelength ultraviolet light, which is called C, however, it can penetrate the skin and eyes, causing cancer and cataracts and other diseases.

Therefore, from the Columbia University medical center in New York physicist David Brenner led a team to test can not penetrate the eye or skin surface far short wave ultraviolet light in the past 4 years. The results showed that far short wave UV light only in addition to kill bacteria on the surface, no harm to rats.

In addition, the researchers pointed out that in December 28, 2017 released on biological preprint website bioRxiv a pre printed Research Report, Brenner and colleagues conducted the next test, to confirm whether it can solve the far short ultraviolet radiation in many public places are the major health problems: planktonic bacteria.

First of all, the team of atomization of the influenza virus in the test box, and then use the short wavelength of 222 nm UV light irradiation, the virus was used as control, there are no short exposure to ultraviolet light. Since then, the researchers collected from the test box and the liquid sample spread in susceptible to influenza infection in dogs in kidney cells, the results show that the sample has not been short of ultraviolet irradiation can infect cells, and after UV irradiation is not short.

Industrial hygienists Shawn Gibbs believes that if the research is successful, it will have a positive effect on the short wave ultraviolet light disturbs the spread of disease. It is understood that the performance of Shawn Gibbs has studied the short disinfection ultraviolet at the University of Indiana School of public health in Bloomington. (compiled: LEDinside Janice)
