Potential of ethanol gas sensors in biomedical applications

Abstract

A major problem in the medical field is detecting one or another disease. To make a fast decision and apply the correct treatment, it is necessary to understand the exact problem. Thus, many researchers respond to the challenge of detecting different diseases beforehand using distinct biomarkers. Various researchers in this field are motivating others to make corresponding sensors and to comply with the actual necessities. In this direction, appealing research is on ethanol gas sensors, which have the potential to show several diseases. While there are multiple technologies for gas sensors, such as optical sensors and electrochemical cell-based with good results, a promising approach could be metal-oxide based sensor.
