“…PADs provide several advantages, including low manufacturing cost, simplicity, portability, small sample volume, and ease of handling, making them attractive for use in many applications including clinical diagnostics and food safety analysis [ 17 ]. In addition, a white paper is a good substrate for colorimetric detection because it gives strong contrast with a color, allowing results to be assessed directly by naked eyes [ 26 ]. To apply paper as an analytical tool for the detection of bacterial H 2 S, we designed a multi-zone patterned form that was easily fitted to each well in the microplate.…”

Hydrogen sulfide (H2S) is known to participate in bacteria-induced inflammatory response in periodontal diseases. Therefore, it is necessary to quantify H2S produced by oral bacteria for diagnosis and treatment of oral diseases including halitosis and periodontal disease. In this study, we introduce a paper-based colorimetric assay for detecting bacterial H2S utilizing silver/Nafion/polyvinylpyrrolidone membrane and a 96-well microplate. This H2S-sensing paper showed a good sensitivity (8.27 blue channel intensity/μM H2S, R2 = 0.9996), which was higher than that of lead acetate paper (6.05 blue channel intensity/μM H2S, R2 = 0.9959). We analyzed the difference in H2S concentration released from four kinds of oral bacteria (Eikenella corrodens, Streptococcus sobrinus, Streptococcus mutans, and Lactobacillus casei). Finally, the H2S level in Eikenella corrodens while varying the concentration of cysteine and treatment time was quantified. This paper-based colorimetric assay can be utilized as a simple and effective tool for in vitro screening of H2S-producing ability of many bacteria as well as salivary H2S analysis.

“…H 2 S is present in exhaled breath in the ppb range and can be detected by gas chromatography, mass spectrometry, different electrochemical sensors and by other sensitive techniques [ 169 , 180 , 181 , 182 , 183 , 184 , 185 , 186 ] ( Table 2 ). Furthermore, the human nose can detect smell if sulfide is present in the ppb range [ 184 , 187 ].…”

Cancers, chronic diseases and respiratory infections are major causes of mortality and present diagnostic and therapeutic challenges for health care. There is an unmet medical need for non-invasive, easy-to-use biomarkers for the early diagnosis, phenotyping, predicting and monitoring of the therapeutic responses of these disorders. Exhaled breath sampling is an attractive choice that has gained attention in recent years. Exhaled nitric oxide measurement used as a predictive biomarker of the response to anti-eosinophil therapy in severe asthma has paved the way for other exhaled breath biomarkers. Advances in laser and nanosensor technologies and spectrometry together with widespread use of algorithms and artificial intelligence have facilitated research on volatile organic compounds and artificial olfaction systems to develop new exhaled biomarkers. We aim to provide an overview of the recent advances in and challenges of exhaled biomarker measurements with an emphasis on the applicability of their measurement as a non-invasive, point-of-care diagnostic and monitoring tool.

“…They suggested that the colorimetric paper probe is easy to fabricate, cost-effective, disposable, and a green alternative to the commonly used lead acetate test papers. Recently, Ahn et al [ 72 ] developed a rapid and simple colorimetric paper sensor using an etching-resistant effect on Ag nanoprisms. The detection principle was that Ag NPRs on the paper reacted with H 2 S gas to form Ag 2 S on their surfaces, which induced etching-resistant Ag NPRs against Cl − ions.…”

Hydrogen sulfide (H2S) plays an important role in mammals as a signaling molecule. Recently, abnormal H2S concentration has been associated with several pathophysiological states, such as diabetes mellitus, hypertension, Alzheimer’s disease, and Parkinson’s disease. As regulating H2S concentration can be a very prominent way of developing new drugs, many researchers have paid great attention to H2S research. To understand the role of H2S in pathophysiology and develop H2S-based therapies, it is necessary to measure the exact concentration of H2S within biological systems. But, H2S is volatile and can be easily oxidized. Besides, the active sites for several biological effects of H2S are inside the cell. Therefore, there is a need for the development of new methods for the accurate and reliable detection of H2S within live cells. This review provides a summary of recent developments in H2S detection methods for live cell analysis.
