“…The self-calibration function of ratio detection and the low interference of near-infrared dye improved the accuracy and reliability. In 2021, Fan et al [ 87 ] constructed a ratio fluorescence H 2 S sensor with surfactant structure based on fluorescence resonance energy transfer (FRET). Dansyl-based derivative (DBr) is the FRET donor, pyronine Y (PyY) is the FRET receptor and H 2 S reaction site and particularly adopted cationic hexadecyltrimethylammonium bromide (CTAB) micelles to encapsulate and modulate the fluorophores.…”

As the third gasotransmitter, hydrogen sulfide (H2S) is involved in a variety of physiological and pathological processes wherein abnormal levels of H2S indicate various diseases. Therefore, an efficient and reliable monitoring of H2S concentration in organisms and living cells is of great significance. Of diverse detection technologies, electrochemical sensors possess the unique advantages of miniaturization, fast detection, and high sensitivity, while the fluorescent and colorimetric ones exhibit exclusive visualization. All these chemical sensors are expected to be leveraged for H2S detection in organisms and living cells, thus offering promising options for wearable devices. In this paper, the chemical sensors used to detect H2S in the last 10 years are reviewed based on the different properties (metal affinity, reducibility, and nucleophilicity) of H2S, simultaneously summarizing the detection materials, methods, linear range, detection limits, selectivity, etc. Meanwhile, the existing problems of such sensors and possible solutions are put forward. This review indicates that these types of chemical sensors competently serve as specific, accurate, highly selective, and sensitive sensor platforms for H2S detection in organisms and living cells.

“…The sensing technique is based on the change of apparent color of the signal due to the presence of a particular analyte. This variation can be the result of the change in the relative intensity of two emission bands, [43][44][45] or the spectral shift of a single band that moves to a distinct color channel. [46] This change in the apparent color can be detected by the naked eye, which gave rise to simple detection techniques that do not require a mechanic detector.…”

Fluorescent microscopy has enabled the study of intracellular processes and revealed the most intricate details of the subcellular structure. This has benefitted not only the basic biological science, but also has had an impact in numerous biomedical applications. Basic fluorescent sensing techniques use the change in the absolute emission of a fluorescent sensor. This entails some disadvantages as the signal might be influenced by factors not directly related to the process under study (e.g., fluctuations in the excitation source). To overcome these drawbacks, one can use multiple emissions of a single or various fluorophores. There are numerous examples of multichannel fluorescence microscopy techniques that have given rise to numerous ratiometric methods and multiplexing assays. Herein, how the use of multiple emission channels has impacted fluorescence microscopy in terms of speed, sensitivity, and resolution is reviewed. Using recent examples, how the easy implementation of multichannel detection can overcome current limitations of the main used fluorescence techniques and promote the development of novel microscopy methods is shown.

“…Ding's group firstly synthesized an H 2 S ratiometric fluorescence probe through a simple surfactant aggregate-encapsulation strategy. [80] In the system, a novel one-step synthesized dansyl derivative (DBr) can serve as a fluorescence resonance energy transfer (FRET) donor and commercially available pyronin Y (PyY) as both energy acceptor and H 2 S response site (Figure 5A). Compared to other FRET-based probes, this probe is relatively easy to build, and this work provides a new approach for ratiometric fluorescence probes based on non-covalent ensembles.…”

Hydrogen sulfide (H2S) is an important endogenous biological signal molecule that plays an essential role in various pathological and physiological processes. Abnormal expression of H2S in vivo is associated with the occurrence and development of many diseases. Therefore, sensing biological H2S level and distribution is significant and has been extensively studied presently. A few reviews about H2S sensing and imaging have been reported, most of which focus on the sensing mechanisms and construction of probes. In this review, we firstly summarized and classified the H2S‐activated fluorescent probes over the past 5 years according to sensing modality and then mainly discussed their biological applications, including detection of physiological and pathological processes, diagnosis of diseases, and disease treatments. It is expected that this review can deepen the readers′ understanding of the biological role of H2S and provide them with biomedical background knowledge for the construction of the H2S probes.
