Nearly all animals are capable of sensing changes in environmental oxygen (O2) and carbon dioxide (CO2) levels, which can signal the presence of food, pathogens, conspecifics, predators, or hosts. The free-living nematode Caenorhabditis elegans is a powerful model system for the study of gas sensing. C.

Gas‐Sensing Transcriptional Regulators
Biotechnology Journal, 2020AbstractGas molecules are ubiquitous in the environment and are used as nutrient and energy sources for living organisms. Many organisms, therefore, have developed gas‐sensing systems to respond efficiently to changes in the atmospheric environment.

Abstract Solid-electrolyte sensors for detecting air pollutants are urgently needed for the sake of environmental protection. Rapid progress is being marked in the development of sensors for CO 2 , NO 2 , NO, SO 2 , ozone and fluorocarbons. Some of them, such as the CO 2 sensor, have almost reached a stage of practical application, while others are ...

This chapter reports a comprehensive review of the nanofiber gas sensor for enabling fast, relatively inexpensive, and minimal monitoring of the target gas concentration. The front part provides detail information on the sensing mechanism, evaluation criteria and application fields of the nanofibers-based gas sensor.

Nanostructured Materials, 1999
We developed a gas sensing CoOSiO2 nanocomposite which changes its optical transmittance by nitrogen oxide. Films prepared by co-sputtering and sol-gel method showed reversible transmittance change by NO at 350 °C in the wavelength range from 400 to 800 nm. Nano-scale cobalt oxide dots were observed in the solCoOSiO2 nanocomposite.

Chemical Communications, 2010
The porous and superhydrophobic shell of a liquid marble prevents contact of its liquid core with outside surfaces, but allows gas transport. Liquid marble can therefore be used to sense gas or emit gas. Liquid marbles loaded with different indicators can simultaneously sense different gases via different mechanisms.

Environmental Gas Sensing with Cavitands
Chemistry – A European Journal, 2017AbstractEnvironmental gas sensing needs stringent sensor requirements in terms of sensitivity, selectivity and ruggedness. One of the major issues to be addressed is combining in a single device the conflicting requirements of molecular‐level selectivity and low‐ppb sensitivity.
