Gas sensors have attracted much research interest over the years. Due to their numerous advantages, they have been used for a wide range of applications; for example, they are small in size, highly sensitive in detecting very low concentrations of gaseous species (at level of ppm or even ppb), can provide online measurements and are low cost. In recent years, the extraordinary progress of nanotechnology has created enormous potential for developing high-performance and miniaturised electronic gas sensors based on electrical, electrochemical, optical and other transduction phenomena. This could lead to lower cost, portable devices with lower power consumption, thus extending the range of their use; for example, in mobiles (cell phones) and wearable applications (watches), as well as in field and remote applications. Finding new sensing materials with peculiar nanostructures is an essential prerequisite to obtain these objectives. Nanostructured materials have, in fact, high surface-to-volume ratio, increased reactivity to gases, charge confinement ability and improved electronic properties, which are key characteristics for designing high-performances gas sensors. These innovative gas sensors could open up mass markets for industry and environmental monitoring, the automotive and biomedical fields, and so on.
This special issue will feature global research that tracks the most recent advances in nanomaterial science which can overcome the challenges of actual gas sensors, such as sensitivity, selectivity, stability and reliability. Both review and original research papers are welcome on all aspects of nanostructured materials; for example:
- New nanostructured materials for gas sensors
- Gas sensors and their functioning principles
- New gas sensor principles and technologies
- Gas sensor-based devices and applications
