Scientists have developed a novel fabrication method to create dyed threads that change color when they detect a variety of gases. Woven into clothing, smart, gas-detecting threads could provide a reusable, washable, and affordable safety asset in medical, workplace, military and rescue environments. The study describes the fabrication method and its ability to extend to a wide range of dyes and detection of complex gas mixtures.
