 Overview:

Measuring the concentrations of gases such as oxygen, carbon monoxide, carbon dioxide, and nitric oxide is of obvious clinical importance as these analytes play key roles in cell function and human physiology. Yet, the development of robust, miniaturized sensors that enable rapid analysis of such gases at relevant concentrations remains a non-trivial endeavor. The objective of this symposium is to provide an overview of recent advances in the design, fabrication, and analytical performance of gas sensors based on unique sensing platforms, with specific emphasis on rapid analysis and miniaturization for probing biological and physiological phenomena. The proposed speaker list was determined based on the speakers' recent work in the development of such sensors for use in biological or biomedical studies. The topics represent a broad range of sensor designs and applications where the ability to measure one or more of the above gases will play a significant role in the monitoring and care of critically ill patients, exhaled breath diagnostics, or single cell analysis.
