Miniaturized Gas Sensing Platforms

Dear Colleagues,

Miniaturized and microfluidic technologies have advanced greatly in the past decade and are an important component supporting innovations in gas detection and monitoring applications. For example, continuous and digital microfluidics can be packaged into miniaturized platforms with precise and automated control over discrete volumes of fluid. Compared to alternative methods, these platforms have several key advantages, including high throughput, repeatability, and requiring less reagent and sample volumes. Benefits of this technology have been demonstrated in various fields of study such as environmental sciences, biotechnology, water quality monitoring, and safety devices. However, fundamental and applied research focusing on miniaturized platforms to pair sample manipulation and delivery systems with various categories and configurations of gas sensors (e.g., metal oxide semi-conductors, electrochemical cells, photoionization detectors, optical sensing, and electronic noses) have not been fully explored. Further investigation is required to determine optimal layouts to interface these technologies. This Special Issue aims to highlight important research and review articles that address challenges and refine methods to create novel developments in miniaturized gas detection platforms. Examples of particular interest include those that demonstrate solutions and devices in areas of safety monitoring, quality control (e.g., food and beverage), screening for controlled substances, and breath-analysis to detect disease biomarkers and monitor overall health.
