Light therapy kills the virus that causes disease

With the advancement of modern medicine, there are many ways to limit the harmful effects of viruses on health. The light therapy that US scientists are studying is considered to be one of the effective methods of eliminating pathogenic viruses that help usher in new applications in the future.

To prevent the risk of infection, doctors often advise each person to: clean his hands often, eat lots of fruits and vegetables, pay attention to personal hygiene, sleep a lot and do not use his hands to rub his eyes. However, these common measures help to prevent the risk of infection is very limited and only work for some common bacteria and viruses such as influenza virus, Rubella, Ebola bacteria, E. coli.

In the meantime, there are many types of viruses and strains that cause serious illnesses and must be treated with antibiotics or vaccines for prevention. However, today, the transformation of viruses and bacteria is leading to increasing resistance to drugs and vaccines. Facing the threat of human health, scientists in many countries around the world have studied many different ways to kill bacteria before experimenting with light therapy .

In the future, laser light will be used in killing viruses
causes disease and does not cause damage to cells in the body.

Ultraviolet ray therapy

Most of the dangerous viruses can be destroyed by using laser beams, but scientists' research also says that not all viruses have the same structure. Therefore, the use of this type of light for some viruses can be effective, but if used with other viruses may not work.

During the study to find new ways to kill the virus, US scientists have been successful in experimenting with UV ultraviolet light therapy. Currently UV sterilization method is being applied in some countries around the world.

Although this type of light can cause sunburn and increase the risk of skin cancer in humans, it can effectively kill the virus. Just like when lighting lasers, when shining ultraviolet rays on some viruses, their outer shell is broken so that the virus falls into a state of inactivity and cannot continue to attack the cells in the muscle. human being.

This achievement is currently being applied in air filtration, deodorization and ultraviolet water filtration systems to prevent airborne pathogens and in water sources. In addition, it can be used in food sterilization systems that effectively kill E. coli while ensuring the quality and taste of food.

The application of ultraviolet rays in the virus and pathogenic bacteria in medicine is also being implemented in developed countries, however, according to the assessment of scientists, due to the characteristics of UV rays are destructive. More than laser beams, it can easily cause viruses to mutate and also affect healthy cells in the body.

Laser anti-virus therapy

Scientists at Arizona State University Research Institute, USA, and their colleagues at John Hopkins University have recently published their study of using light in killing viruses and bacteria. sick. Accordingly, the type of light that was once considered an important discovery of science - laser light - is not only capable of being applied in the industrial and military fields . but also can be used to kill and kill bacteria. virus effective.

In her study, Dr. Kong Thon Tsen - University of Arizona succeeded in destroying the pathogen virus with a purple laser. With ultra-fast laser beams in 100 femtoseconds (1 femtosecond is 1 millionth of a billionth of a second), laser light can significantly impact the outer shell of the virus. This is very important for completely destroying the virus because the virus will then become harmless while the cells in the body are still protected.

Scientists hope that, after the end of these tests, this achievement could be applied in the treatment of a wide range of dangerous viral-related diseases, including the HIV / AIDS disease caused by the HIV virus. Out and hepatitis. By scanning laser beams to clean up viruses and other pathogens in the blood, scientists can completely eliminate disease-causing viruses in the patient's body quickly. In addition, laser therapy can be easily combined with other current treatments. In that case, the doctor will use the device to remove part of the blood from the body for laser cleaning, then transfer it back to the patient's body like an artificial dialysis process.
