Color-Changing Condoms That Detect STIs

Three young teenagers from the Isaac Newton Academy in Ilford, Essex have created condoms that change color after coming into contact with a sexually transmitted infection. Daanyaal Ali, Muaz Nawaz and Chirag Shah developed the clever contraceptives—dubbed “S.T.EYE”—to make “detecting harmful STIs safer than ever before, so that people can take immediate action in the privacy of their own homes.” TeenTech has awarded the young inventors with £1,000 and a trip to Buckingham Palace for “best health innovation.”
