The effects of nitric oxide in biological systems depend on its steady-state concentration and
where it is being produced. The organ where nitric oxide is produced is relevant, and within …

Exhaled breath‐based disease diagnosis is an ancient technique, and the application of this
technique is rapidly developing for disease quick testing, such as viral infection, asthma …

Mobile applications based on gas sensing present new opportunities for low-cost air quality
monitoring, safety, and healthcare. Metal oxide semiconductor (MOX) gas sensors represent …

Background Fractional exhaled nitric oxide (FENO) is a useful and noninvasive biomarker
for eosinophilic airway inflammation, particularly in asthma. However, its utility in chronic …

Airway inflammation in chronic obstructive pulmonary disease (COPD) is typically thought to
be driven by Type1 immune responses, while Type2 inflammation appears to be present in …

Breath analysis provides a convenient and simple alternative to traditional specimen testing
in clinical laboratory diagnosis. As such, substantial research has been devoted to the …

The analysis of biomarkers in exhaled breath constituents has recently become of great
interest in the diagnosis, treatment and monitoring of many respiratory conditions. Of …

This review describes the unique links of the functioning of the nitric oxide cycle in the
respiratory tract in normal and pathological conditions. The concept of a nitric oxide cycle …

We successfully demonstrated a simple and low-cost nitric oxide (NO) gas sensor to deliver
parts-per-billion (ppb) regime detection at room temperature operation. A vertical-channel …

Chronic obstructive pulmonary disease (COPD) is the most common fixed airflow limitation.
Individuals may present with the features of both asthma and COPD called asthma-COPD …
