Sulfite is a common food additive that prevents oxidation from damaging food nutrients, and it has long been used in the food industry as a bleaching agent. It can harm the human body if taken wrongly or excessively. In this study, three dyes (cresol red, chlorophenol red, and bromocresol green) were explored to analyze the presence of sodium sulfite (SS) in an inexpensive, disposable paper sensor with a lower visible detection limit of 0.05 M. This visual paper sensor detects sodium sulfite with high selectivity and sensitivity at room temperature. An IoT-based sensor was also developed to practically apply the developed method, which is rapid and low-cost and can replace heavy-duty instruments. Both these sensors can substantially impact scenarios such as food quality monitoring and detecting sodium sulfite in medicinal items. Graphical Abstract

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, chronic kidney disease, and so on. Among the diagnostic tools, an exhaled breath‐based test has demonstrated the merits of being non‐invasive, convenient, quick, and comfortable. In this review, the exhaled breath diagnosis via the gaseous part of the breath is the major focus. First, the summary of state‐of‐art studies based on exhaled gas detection is described. Second, typical disease‐related exhaled gas and their measurements are described. Finally, the various structure of field effect transistor (FET)‐type sensors for gas‐based disease detection is discussed in detail. This review may inspire new research ideas and directions for applying FET‐type sensors to quick disease detection via the gaseous route.
