At just 17, Dasia Taylor from Iowa City West High School developed an innovative solution that could transform post-surgery care. While studying how infections affect the body, she focused on changes in pH levels, as healthy skin is slightly acidic but becomes more alkaline when infected.
Using this concept, she created surgical stitches coated with beetroot extract, a natural pH indicator. The stitches remain red on healthy skin but shift to a darker purple when infection begins, offering a simple visual warning without expensive equipment.
Her invention is especially promising for low-resource settings, where access to advanced diagnostic tools is limited and early detection can save lives.
Taylor’s work earned her recognition as a finalist in the Regeneron Science Talent Search 2021, along with a special peer award. She has also taken steps toward securing a patent, aiming to bring this low-cost innovation to global healthcare systems.
