17-year-old Dasia Taylor was named one of 40 finalists in the Regeneron Science Talent Search(STS)（雷杰纳隆科学奖）, the nation’s most famous science and math competition for high school seniors.
Dasia’s sutures（缝合线） work by changing color if the patients pH level changes, indicating an infection. PH is one of the most common parts of wound healing, Dasia said. It changes very quickly, so it’s one of the fastest ways to recognize infection.
So, she started experimenting with root vegetables. "I found that beet(甜菜) changed color at the perfect pH point," says Taylor. "That's perfect for an infected wound. And so, I was like, 'Oh, okay. So beet is where it's at’. Beet provided the perfect dye for her invention, changing from bright red to dark purple when a surgical wound becomes infected. After more than a year of research, Taylor is working on getting her sutures patented.
She imagines these sutures being used in developing countries where they can save lives and money. "The goal of my project is to reduce the number of deadly surgical site infections in developing countries because developing countries suffer from the most number of deaths due to surgical site infections," she said. "I was like there is no way that that should be happening. The equity part of my brain and all the work that I do around equity was like 'That shouldn't be happening. They should have the resources to save their citizens in their country.' So, my goal is to work on that and make sure that it can actually discover those types of infections and stuff." After graduation, Dasia hopes to attend Howard University, study political science and finally become a lawyer.
