Summary: In this study, a novel n-n heterogeneous MoS2/SnO2 nanotubes were prepared and utilized for triethylamine (TEA) sensing. The MoS2/SnO2 sensor showed excellent selectivity and high response to TEA, with a detection limit as low as 1 ppm. The sensing mechanism was found to be due to the synergistic effect of n-n type heterojunctions and unique tubular nanostructure.

Summary: Various temperature sensitive biological mechanisms have been used in new biomedical engineering tools such as neuromodulation, cancer cell hyperthermia, or photothermal therapy. Transparent and high spatio-temporal resolution temperature sensors are needed to analyze biological effects accurately in response to temperature changes. Transparent temperature sensors with micro-scale spatial resolution are useful for cellular resolution bio-imaging, optical neural recording, and optical bio-modulation where transparency and high-resolution temperature sensing are required.

Summary: Detection of ethanol is crucial in various fields due to its explosive, colorless and volatile nature. Metal oxide semiconductors (MOS) gas sensors, particularly those based on indium oxide (In2O3), have gained attention for their low cost and convenient detection. This paper summarizes the strategies used in the last decade to enhance the performance of In2O3-based gas sensors for ethanol detection, including morphology modification, doping, heterojunction construction, and the use of composite materials. The sensing mechanism for ethanol detection by gas sensors is also presented.
