A Critical Review on Uses of Gases in Veterinary Medicine and Gas Sensing Materials

Abstract

In modern therapeutics, various gases are used as driving sources for ventilators and nebulizers. Medical gases are used in veterinary medicine and the biological sciences, including treating respiratory problems, managing strokes, preserving biological samples, anesthesia, organ cryopreservation, for forensic examinations, and for driving medical equipment and tools. In veterinary biotechnology, bovine sperm is often cryogenically preserved using liquid nitrogen. Here we attempt to give a broad overview of the implications of several gases used in biological and veterinary science. In the next part of this article, we will focus on the meaning of gas sensors, their types and functions. Detecting specific gases and their concentrations has become important for monitoring the environment, ensuring public safety, addressing health concerns, controlling chemical processing, and using gas molecules in agriculture and medicine. Materials for gas sensing have a long history of development. With advances in nanoscience and technology, researchers have effectively developed a number of transition metal oxides that can be used as gas-sensitive materials. Here, we discuss various materials used as gas sensors. Finally, the research progress of gas sensitive materials in recent years is discussed.
