A Paper-Based Ultrasensitive Optical Sensor for the Selective Detection of H<sub>2</sub>S Vapors

A selective and inexpensive chemical paper-based sensor for the detection of gaseous H<sub>2</sub>S is presented. The triggering of the sensing mechanism is based on an arene-derivative dye which undergoes specific reactions in the presence of H<sub>2</sub>S, allowing for col...
