Article Synopsis
- Colorimetric sensors are useful for gas monitoring as they detect gas presence through visible color changes, but creating highly sensitive versions has been a challenge.
- This study developed a sensitive colorimetric sensing yarn by combining anthocyanins dye with wool powder, significantly enhancing its sensitivity to ammonia (NH) gas.
- The yarn's detection limit improved from 100 ppm to 20 ppm, and the response time decreased from 2 minutes to just 20 seconds, showcasing potential for effective toxic gas monitoring in wearable devices.
