“…The OA‐capped UCNPs were prepared as per the earlier reported procedure with slight modification ,. Owing to the hydrophobic host‐guest interaction, hybrid RePr ‐UCNPs were effortlessly prepared through self‐assembly method . Due to hydrophilic rim of α‐CD, RePr ‐UCNPs were easily dispersed in aqueous solutions, which is a requirement for the detection of analytes in water medium.…”

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.

“…In this regard, several optical chemosensors have been developed for natural amino acids (Buryak and Severin, 2005;Ma et al, 2013;Yin et al, 2013;Sener et al, 2014;Ghasemi et al, 2015;Meng et al, 2015;Chao and Zhang, 2017;Gholami et al, 2019;Liu et al, 2019;Xu et al, 2020). However, these chemosensors require complicated synthetic processes (Yang et al, 2011;Song et al, 2016;Yang et al, 2018), which limit their practical usage in real-world scenarios. Chemosensor arrays by supramolecular interactions with pattern recognition can avoid the synthetic processes and simultaneously quantify multiple analytes (Cao et al, 2020;Sasaki et al, 2021a;Sasaki et al, 2021b;Lyu et al, 2021).…”

Toward Food Freshness Monitoring: Coordination Binding–Based Colorimetric Sensor Array for Sulfur-Containing Amino Acids

et al. 2021

Herein, a self-assembled colorimetric chemosensor array composed of off-the-shelf catechol dyes and a metal ion (i.e., Zn2+) has been used for the sulfur-containing amino acids (SCAAs; i.e., glutathione, glutathione disulfide, L–cysteine, DL–homocysteine, and L–cystine). The coordination binding–based chemosensor array (CBSA) fabricated by a competitive assay among SCAAs, Zn2+ ions, and catechol dyes [i.e., pyrocatechol violet (PV), bromopyrogallol red (BPR), pyrogallol red (PR), and alizarin red S (ARS)] yielded fingerprint-like colorimetric changes. We succeeded in the qualification of SCAAs based on pattern recognition [i.e., a linear discrimination analysis (LDA)] with 100% correct classification accuracy. The semiquantification of reduced/oxidized forms of SCAAs was also performed based on LDA. Furthermore, we carried out a spike test of glutathione in food samples using the proposed chemosensor array with regression analysis. It is worth mentioning that we achieved a 91–110% recovery rate in real sample tests, which confirmed the accuracy of the constructed model. Thus, this study represents a step forward in assessing food freshness based on supramolecular analytical methods.

“…Lanthanide‐doped upconversion nanoparticles under low levels of near‐infrared (NIR) light excitation could convert long‐wavelength stimulation into short‐wavelength emission, absorbs low energy NIR radiation and transfers this energy to visible light . In comparison with the traditional organic fluorophores and inorganic nanoparticles, lanthanide‐doped upconversion nanomaterials feature several attractive optical properties due to their unique anti‐Stokes fluorescence properties, such as a narrow emission band, low toxicity, high chemical stability, deep tissue penetration and weak autofluorescence backgrounds .…”

An redox luminescence switch was developed for the sensing of glutathione (GSH), l-cysteine (Cys) or l-ascorbic acid (AA) based on redox reaction. The Mn -doped NaYF :Yb,Er upconversion nanorods (UCNRs) with an emission peak located in the red region were synthesized. The luminescence intensity of the UCNRs could be quenched due to the Mn could be oxidized to MnO by KMnO . Subsequently, when the AA, GSH or Cys was added into the MnO modified upconversion nanosystem, which could reduced MnO to Mn and the luminescence intensity was recovered. The concentration ranges of the nanosystem are 0.500-3.375 mM (R = 0.99) for AA, 0.6250-11.88 mM (R = 0.99) for GSH and 0.6250-9.375 mM (R = 0.99) for Cys, respectively.
