A Durham company is developing a new technology that will help fight COVID-19. It’s what EmitBio said will potentially save millions of lives. The handheld device is inserted into the mouth aims precise wavelengths of targeted light at a spot in the back of the throat known as your oropharynx. It’s turned on for five minutes, and later that same day the treatment is repeated. The light it emits interacts with the cells of the body and COVID-19. “So, the virus wants to make many copies of itself so it’s doing that continuously inside the cell. And we’re able to disable that property and that takes care of everything,” said EmitBio Executive Chairman Neal Hunter. Hunter said the technology stops the virus from making copies of itself. The key is that you need to have mild to moderate symptoms within 72 hours for it to be most effective.
