This Dressing Turns From Yellow to Blue Upon Detecting Infection

A team of scientists at a trio of Swedish universities have developed a futuristic wound dressing that is designed to be able to alert wearers and medical professionals to the potential presence of an infection by changing its color.
This wound dressing is made of a special nano-cellulose mesh that is sheathed in porous silica that is infused with bromthymol blue dye. When an infection occurs, the pH levels of the wound typically increase even before tell-tale symptoms such as swelling make themselves known. When the pH level exceeds a certain point, the BTB dye is transformed from its low-pH yellow color to its high-pH blue.
"Being able to see instantly whether a wound has become infected, without having to lift the dressing, opens up for a new type of wound care that can lead to more efficient care and improve life for patients with hard-to-heal wounds," said professor Daniel Aili of Linkoping University, adding that it could also help reduce reliance on antibiotics.
