Dasia Taylor, a 17-year-old student from Iowa City, has found a way to detect an infected surgical wound.
Dasia found a suture thread that when dyed with beet juice, changes colour from bright red to dark purple, when a surgical wound becomes infected. Taylor's remarkable invention won several awards at regional science fairs and could potentially change the way surgical wounds are sutured.
