description | Ammonia is one of the most frequently produced chemicals in the world, and thus, reliable measurements of different NH(3) concentrations are critical for a variety of industries, among which are the agricultural and healthcare sectors. The currently available technologies for the detection of NH(3) provide accurate identification; however, they are limited by size, portability, and fabrication cost. Therefore, in this work, we report the laser-induced forward transfer (LIFT) of single-walled carbon nanotubes (SWCNTs) decorated with tin oxide nanoparticles (SnO(2) NPs), which act as sensitive materials in chemiresistive NH(3) sensors. We demonstrate that the LIFT-fabricated sensors can detect NH(3) at room temperature and have a response time of 13 s (for 25 ppm NH(3)). In addition, the laser-fabricated sensors are fully reversible when exposed to multiple cycles of NH(3) and have an excellent theoretical limit of detection of 24 ppt. |
