“…Compared with these analytical approaches, the colorimetric and/or fluorescent techniques belonging to spectral field are more suitable, competent and attractive for the detection of hydrazine on account of their high sensitivity, low cost, simplicity, dependability, speediness, real‐time detection and mainly turn‐on fluorescent probes, which not only have easy implementation, high sensitivity and selectivity, but also have a high signal‐to‐noise ratio . These sensing techniques are very much handy to monitor hydrazine in several environmental samples e. g. air, squander water and residues . Additionally, detection with the chromogenic and/or fluorogenic probes constantly associates with ultraviolet or fluorescent emissions, which can be easily detected visually excluding any sophisticated instrumentation.…”

Recently, the design, synthesis and development of chemodosimeters for hydrazine with high selectivity and sensitivity has attracted tremendous attention due to its major contributions to human health and disease including applications in various platforms. In this review, we recapitulate different strategies for the design of reaction‐based colorimetric and fluorometric probes for the detection of hydrazine and their applications in hydrazine sensing in living systems. The sensing strategies for hydrazine have been divided into six categories: (a) cleavage of the acetoxy group; (b) the nucleophilic addition‐elimination on keto ester; (c) the nucleophilic substitution‐elimination to tandem cyclization on halo‐ester; (d) the nucleophilic addition reaction to phthalimide derivative to phthalhydrazide; (e) the chemical displacement of active methylene compound to hydrazone derivative and (f) Other different approaches. Additionally, a variety of techniques have been devised here for the detection of hydrazine over other comparable ions and neutral amines.

“…The developed systems have enabled the detection of target molecules using a fluorescent signal or even by the naked eye in real time . Although there have been numerous applications of fluorescent dyes as reporter systems in sensing platforms, these systems still require improvements to overcome the challenges and disadvantages of sensors …”

Recent chemo‐/biosensor and bioimaging studies based on indole‐decorated BODIPYs

2019

BODIPY is an important fluorophores due to its enhanced photophysical and chemical properties including outstanding thermal/photochemical stability, intense absorption/emission profiles, high photoluminescence quantum yield, and small Stokes' shifts. In addition to BODIPY, indole and its derivatives have recently gained attention because of their structural properties and particularly biological importance, therefore these molecules have been widely used in sensing and biosensing applications. Here, we focus on recent studies that reported the incorporation of indole‐based BODIPY molecules as reporter molecules in sensing systems. We highlight the rationale for developing such systems and evaluate detection limits of the developed sensing platforms. Furthermore, we also review the application of indole‐based BODIPY molecules in bioimaging studies. This article includes the evaluation of indole‐based BODIPYs from synthesis to characterization and a comparison of the advantages and disadvantages of developed reporter systems, making it instructive for researchers in various disciplines for the design and development of similar systems.

“…On the basis of this special chemical reaction, many organic molecules have been developed as fluorometric H 2 S probes. [20][21][22] Azide-caged fluorophores (e.g., sulfonamide and coumarin) have been developed as turn-on fluorescent H 2 S sensors. [23][24][25] To diminish the influence of probe concentration, azide group functionalized cyanine dye and cresyl violet have been synthesized as ratiometric fluorescent H 2 S sensors.…”

Selective Colorimetric Detection of Hydrogen Sulfide Based on Primary Amine-Active Ester Cross-Linking of Gold Nanoparticles

et al. 2015

Hydrogen sulfide (H2S) is a highly toxic environmental pollutant and also an important gaseous transmitter. Therefore, selective detection of H2S is very important, and visual detection of it with the naked eye is preferred in practical applications. In this study, thiolated azido derivates and active esters functionalized gold nanoparticles (AE-AuNPs)-based nanosensors have been successfully prepared for H2S perception. The sensing principle consists of two steps: first, H2S reduces the azide group to a primary amine; second, a cross-linking reaction between the primary amine and active ester induces the aggregation of AuNPs. The AE-AuNPs-based nanosensors show high selectivity toward H2S over other anions and thiols due to the specific azide-H2S chemistry. Under optimal conditions, 0.2 μM H2S is detectable using a UV-vis spectrophotometer, and 4 μM H2S can be easily detected by the naked eye. In addition, the practical application of the designed nanosensors was evaluated with lake water samples.
