DNA Film Can Be Used As A Sunscreen To Protect The Skin From The UV Light By partha das | Jul 27, 2017 11:14 AM EDT Researchers have developed a DNA film that can protect the skin from Ultraviolet light. Users can apply it to the skin for a longer period to acquire better results. Researchers from the Binghamton University, State University of New York have created a unique DNA film or the coating. This coating helps to keep the skin hydrated and protect it from UV light. The interesting fact is sunscreen users can apply it to the skin for a better result. Assistant Professor of the biomedical engineering at the famous Binghamton University, Guy German, has uttered significantly about this coating. According to Guy German, Ultraviolet light damages the DNA, and this is not at all good for the skin. The researchers then planned to flip it by using the DNA as the sacrificial layer, Phys.org reported. Now the UV light could only damage this layer placed on the skin and not the DNA that exists within the skin. In a word, the DNA film will work as a protector of the skin. German and the research team has made a thin and simultaneously optically transparent crystalline DNA film. The team irradiated this DNA film with the Ultraviolet light. The researchers noticed more exposure of the film to the UV light brought better absorption of the light by the film and offered better outcomes. The research report is available in the Scientific Reports. Now Guy German has made it clear that one can use this DNA film as a sunscreen or topical cream. The assistant professor also adds that users can stay longer on the beach and the film must provide better results as a sunscreen. An essential fact is this DNA coating is hygroscopic. That means DNA coatings help the original skin to store and hold water more efficiently than the uncoated skin. DNA film placed on the human skin decreases the water evaporation rate and keeps the tissues of the skin hydrated for a long time. German wants to see if this coating can be used to cover a wound in the hostile environments. Now, German wants to say that if a person could see his wound is healing without removing the DNA film. He also hints that if the coating may help the wound by protecting it from the sun. Apart from these, German is eager to see if the film can provide a moist environment to enhance the healing rates of the wound. In a word, better outcomes could increase the possibility of using this DNA coating to cover the wounds even in the extreme environments.
