Researchers in Brazil are using ultraviolet rays to help eliminate or reduce viruses and bacteria in donated organs before those organs are transplanted into recipients.
When organs are prepared for a typical transplant, the donor’s blood is removed from the organ before it is transplanted. But this does not prevent the transfer of potential viruses or bacteria to the recipient. Instead, by removing the blood and replacing it with a liquid that has been treated with ultraviolet light. The liquid then destroys the cellular membranes of microorganisms like viruses and bacteria, but does not cause similar damage to the organ itself.
