Summary: This study synthesized ZnO and ZnO/Pd nanofibers by electrospinning and determined their sensor properties in the detection of CO, NH3, and H-2 in different oxygen backgrounds. The results showed that in an oxygen-free atmosphere, ZnO/Pd nanofibers exhibited a significant increase in sensor response towards NH3 and H-2, which may be attributed to the formation of palladium hydride, modulation of the potential barrier at the ZnO/Pd interface, and changes in the concentration of donor defects and charge carriers in the ZnO matrix.

Summary: This paper presents a facile screen-printed carbon nanotube electrode on porous polytetrafluoroethylene (PTFE) with room temperature ionic liquid (RTIL) for rapid gas sensing. The sensor showed enhanced electrochemical performance for gas detection and good sensitivity and linearity in tests. Due to the unique porous substrate, the response time of the sensor can be as low as around 14 seconds, making it promising for wearable gas sensing and acute gas exposure alerting.

Summary: Boronate affinity-based indicator displacement assay is a promising approach to develop high performance saccharide sensors, but improving the sensitivity in aqueous solutions has been difficult due to the hydrophilic and hydromimetic nature of saccharides. Inspired by the natural photosynthesis system, an enhanced FRET complex named 4Esculetin-BAAP was designed with high energy donor to acceptor ratio to improve light harvesting efficiency. The sensor array 4EBSA was constructed using complex 4Esculetin-BAAP and showed accurate and sensitive recognition of monosaccharides in both PBS and serum samples. It was also capable of distinguishing glucose and its phosphorylated product in mixed form in serum samples.

Summary: Intraocular pressure (IOP) is a key indicator for glaucoma, and real-time monitoring with microfluidic contact lens sensors offers flexibility, straightforward reading, and low cost. A high-sensitivity microfluidic contact lens sensor based on bilateral wall structure and dyed fish oil as the liquid indicator is developed, showing a sensitivity of 660 mu m/mmHg and a linear regression coefficient of 0.999 in the operating range of 10-30 mmHg. The sensor demonstrates stable response to IOP changes and synchronization with pressure in multiple cycles at a pressure change rate of 3 mmHg/s. With its high sensitivity, linearity, and flexibility, the sensor holds great potential for clinical application of IOP monitoring.
