July 26 (UPI) -- Researchers at Binghamton University in New York have developed a film made of DNA that improves ultraviolet light protection the more it's exposed to it.
"Ultraviolet (UV) light can actually damage DNA, and that's not good for the skin," Guy German, assistant professor of biomedical engineering at Binghamton University, said in a news release. "We thought, let's flip it. What happens instead if we actually used DNA as a sacrificial layer? So instead of damaging DNA within the skin, we damage a layer on top of the skin."
