“…In an attempt to further improve the performance of our devices, we have added a second sensitive layer of poly(3heexylthiophene-2,5-diyl) (P3HT) between the substrate and the CNTs. We were able to enhance the sensing performance of CNT-based gas sensors and improve the recovery to the baseline after the exposure to NH 3 (Figure 3b) [31].…”

Carbon nanotubes are a promising sensing material for bio-transduction devices, due to their unique electrical properties, nanosize, bio-compatibility, and their simple low-cost processability. In this contribution, we present two classes of devices (i.e., electrolyte-gated field-effect transistorbased sensors and gas sensors) fabricated by facile and scalable spray deposition of water-based carbon nanotube inks. The developed sensing platforms have been employed for the detection of several analytes for different applications, including food quality assessment, physical activity monitoring, environmental monitoring, and detection of gaseous species.

Gas sensors for ammonia (NH3) play a crucial role in the maintenance of air quality, preservation of the atmosphere, and evaluation of human health. However, the endeavor to attain a high level of sensitivity in detecting NH3 under ambient conditions remains a challenging task. In this work, poly(3‐hexylthiophene)s and titanium dioxide (P3HT‐TiO2) heterostructure NH3 gas‐sensitive material was prepared, and by drop‐casting the material onto a substrate with Au interdigital electrodes, a sensor for high‐response detection of NH3 at room temperature was constructed. The designed gas sensor exhibited a high response signal of 114.61% toward 15 ppm NH3 at room temperature (25°C) with good reproducibility, strong long‐term stability, and excellent selectivity. Moreover, by analyzing the response law of the sensor under different humidity conditions, it has been noted that both excessively high and excessively low levels of humidity adversely affect the sensor’s response. The remarkable increase in NH3 sensing properties is attributed to the synergistic enhancement effect of P‐N heterojunction formed between P3HT and TiO2. This NH3 gas sensor exhibits tremendous potential for use due to its straightforward structure and outstanding ammonia sensing performance.
