“…The huge number of physiological functions in which N 2 H 4 is involved requires the development of simple methods for its sensitive and selective detection. Up to now, several conventional analytical techniques, including electrochemical methods (such as coulometry, capillary electrophoresis, ion‐selective electrode, potentiometry and amperometry), chromatographic methods (such as HPLC, gas chromatography, and ion chromatography), and titrimetry, have been exploited for both qualitative and quantitative estimation of hydrazine. However, most of these methods generally require costly equipment, skilled operators, time consuming and complicated sample preparation which makes them impractical for real‐time and on‐site analysis.…”

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.

Upconversion Luminescent Material‐Based Inorganic‐Organic Hybrid Sensing System for the Selective Detection of Hydrazine in Environmental Samples

Hydrazine is a noxious environmental pollutant, which can be easily absorbed through skin, respiratory and oral paths of exposure and leads to mutagenic and carcinogenic diseases, which demands for the progress of advanced detection methods. In this regard, we report a new detection platform based on luminescence resonance energy transfer (LRET) for the detection of hydrazine (N 2 H 4 ) in environmental samples, where anti-Stokes shift luminescence having optical sensing system is built with upconversion nanophosphors (UCNPs, donor) modified by resorufin propionate (RePr, acceptor). Herein UCNPs were used as an excitation host to significantly minimize the photobleaching of RePr. Upon interaction with N 2 H 4 , the green upconversion luminescence (UCL) intensity of hybrid nanoprobes (RePr-UCNPs) gradually decreases, since the green emission is in resonance with the absorbance of resorufin, whereas the red emission intensity was intact. Hence, green emitting optical sensing system shows red luminescence in the presence of hydrazine. This organic-inorganic hybrid sensing system has been utilized for the sensing of hydrazine in various environmental samples and the obtained results are compared with the sensing efficiency in distilled water. This anti-Stokes shift luminescent hybrid sensing system would be a promising candidate to be utilized in environmental protection, water treatment and safety inspection.
