An Iowa high schooler invented an infection-detecting suture. Now she’s a CEO.
Well done to Iowa City West High School student Dasia Taylor, one of the finalists in the Regeneron Science Talent Search. Her beautifully simple idea: sutures that change color to indicate if a surgical wound becomes infected. She found that juice from ordinary beets turned from bright red to dark purple if the wound becomes more acid, as happens under infection. Her invention is less expensive than today's solutions, making it more accessible to doctors and patients in low-income countries.
