“…The WHO reports that a few breaths at concentration of 700 mg/m 3 can be fatal [ 116 ]. In addition, this gas plays an important role in mammals, being the third gasotransmitter discovered after NO and CO. H 2 S produces various signaling effects in almost every system such as the cardiovascular or central nervous system [ 117 ].…”

Pollution in cities induces harmful effects on human health, which continuously increases the global demand of gas sensors for air quality control and monitoring. In the same manner, the industrial sector requests new gas sensors for their productive processes. Moreover, the association between exhaled gases and a wide range of diseases or health conditions opens the door for new diagnostic applications. The large number of applications for gas sensors has permitted the development of multiple sensing technologies. Among them, optical fiber gas sensors enable their utilization in remote locations, confined spaces or hostile environments as well as corrosive or explosive atmospheres. Particularly, Lossy Mode Resonance (LMR)-based optical fiber sensors employ the traditional metal oxides used for gas sensing purposes for the generation of the resonances. Some research has been conducted on the development of LMR-based optical fiber gas sensors; however, they have not been fully exploited yet and offer optimal possibilities for improvement. This review gives the reader a complete overview of the works focused on the utilization of LMR-based optical fiber sensors for gas sensing applications, summarizing the materials used for the development of these sensors as well as the fabrication procedures and the performance of these devices.

“…Fluorescence-based detection provides excellent sensitivity, high selectivity, and real-time H 2 S monitoring not only within living cells but also within subcellular organelles. Therefore, the progress of H 2 S-specific fluorescence probes is regarded one of the fastest-growing areas in the field of H 2 S biology [ 58 ]. Although fluorescence-based detection has attracted immense attention for detecting H 2 S inside living cells, it is essential to use expensive instruments and special H 2 S probes for live cell fluorescence detection.…”

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.

“…Researchers often use Western blot, immunohistochemical staining, and some other methods to detect the H 2 S changes indirectly. Recently, there are some direct techniques to detect H 2 S, such as chromatography, electrochemistry and colorimetry 11 . But a technique that can detect H 2 S directly in living cells is still needed.…”

Periodontitis, one of the most common chronic inflammatory diseases, affects the quality of life. Osteogenesis plays an important role in the disease. There is a connection between hydrogen sulfide (H2S) and periodontitis, but according to the study has been published, the precise role of H2S in inflammation remains in doubt. The main reason for the lack of research is that H2S is an endogenous gasotransmitter, difficult to discern through testing. So, we synthesized a novel fluorescence probe which can detect H2S in vitro. By using the novel H2S fluorescence probe, we found that H2S changes in osteoblasts mainly by cystathionine-γ-lyase, and H2S increases under LPS stimulation. H2S could be a potential marker for diagnosis of inflammatory diseases of bone, and might help deepen studies of the changes of H2S level and promote the progression on the researches about pathogenesis of periodontitis.
