In an emergency such as a factory fire, ascertaining which gases are present in the air is critical to preventing or minimizing poisoning (Fig. 1). This requires gas sensors that react quickly and provide a visual signal. However, many existing detection systems work for only one gas, or they use a chemical reaction that is too slow to respond in emergency situations.
