These colour-changing sutures can catch infections

Summary

This article, published by freethink, tells the story of an Iowa teenager Dasia Taylor who has developed a concept of colour-changing sutures to warn of infection. Skin pH levels typically hover around 5, but an infection can cause pH to spike. When it does, Taylor's colour-changing sutures, dyed with beet juice, go from red to purple. 

inspired by the concept of 'smart sutures' Taylor wanted to look at doing something that would be more accessible to developing countries. The hope is that hopes the sutures will help spot infections early, when antibiotics can treat them, instead of more invasive measures.
