“…In order to investigate the potential application of the Cd-nanosheet for the sensing, − the Cd-nanosheet was dispersed in dimethylformamide (DMF) solvent containing different metal cations (K + , Na + , Ba 2+ , Cd 2+ , Ca 2+ , Mg 2+ , Mn 2+ , Zn 2+ , Pb 2+ , Co 2+ , Hg 2+ , Al 3+ , and Cu 2+ ) at a concentration of 1 mg/mL. After standing it for 24 h at 25 °C, the Cd-nanosheet was fully dispersed in suspensions containing various metal ions by ultrasound for 30 min.…”

A cadmium(II) coordination polymer nanosheet (Cd-nanosheet) has been successfully constructed by a liquid–liquid interface-assisted method based on the coordination reaction between 1,3,5-tri(4-(2,2’:6′,2″-terpyridyl)phenyl)benzene and cadmium(II) nitrate. The Cd-nanosheet was characterized by elemental analysis, FT-IR spectroscopy, XPS, and fluorescence spectroscopy. The expected 2D lamellar structure was also confirmed by various microscopic techniques. The Cd-nanosheet is insoluble in aqueous and organic solvents. Due to its excellent fluorescence performance, we focus on its application in the detection of organic small molecules and metal ions. The luminescence quenching constant Ksv of the Cd-nanosheet for Cu2+ ions and nitrobenzene is 4.73 × 104 and 2.582 × 103 M–1, respectively. The results demonstrate that Cd-nanosheets can serve as detection sensors with high selectivity and sensitivity to detect nitrobenzene and Cu2+ ions.

“…Common methods for the detection of MG include high‐performance liquid chromatography (HPLC) (Chen & Miao, 2010), liquid chromatography–mass spectrometry (Tao et al, 2011), fluorescence spectroscopy (Hu et al, 2021; Kong et al, 2022; Ma et al, 2022), capillary electrophoresis (Luo et al, 2010), surface‐enhanced Raman scattering (Neng et al, 2010; Tan et al, 2012), ultraviolet–visible light (UV–vis) spectrophotometry (Zhao et al, 2020), and electrochemical aptamer sensing (Yu et al, 2021). However, these methods can only detect relatively large volumes of residues, have a low sensitivity for trace residues, and cannot perform rapid or high‐throughput detection (Feng et al, 2015; Shu & Tang, 2019).…”

Malachite green (MG), a triphenylmethane dye is often used as a fungicide and preservative in fisheries due to its effectiveness against water molds in fish and fish eggs. However, excessive inhalation can be hazardous to human health. To quantify the MG concentration, we created and evaluated a 96‐well plate‐based chemiluminescence immunoassay (CLIA). This method used provided readings in <30 min, with an optimal incubation time of 15 min and a limit of detection of 0.20 ng·ml−1. The strong correlation (R2 >0.99) between the measured values of real fish samples examined using the method and the high‐performance liquid chromatography results confirmed the accurate quantitative detection of MG. In this study, CLIA was also used in conjunction with point‐of‐care testing (POCT) to greatly improve the efficiency of the experiments. Thus, a quantitative detection method based on MG plate chemiluminescence was established herein, with performance indexes that meet the requirements of on‐site detection. This approach is also applicable to the detection of small molecule compounds such as chloramphenicol and sulfadiazine pyrimethamine, providing a new direction in the field of food safety detection.

“…Metal–organic frameworks (MOFs) constructed from metal ions/clusters and organic struts have gained attention due to their various application areas such as gas adsorption, dye/heavy metal adsorption, sensors, etc., and tunable properties. − Among these application areas, luminescent MOFs have been widely preferred to detect metal ions, antibiotics, some explosive compounds, etc., due to their fast response time, high sensitivity, and low cost in chemosensor studies. − Among these analytes, nitroaromatic compounds (NACs) are not only secondary explosives but also widely used in the industry. , NACs, which are environmentally toxic, can cause health problems to the human when discharged into the environment. − Hence, detection studies for NACs have been carried out with MOFs. − …”

An anionic Cd(II) metal–organic framework, {[NH2(CH3)2]2[Cd(μ4-TDBAT)]·3H2O·DMF} n (1) (TDBAT: 5,5′-((thiophene-2,5-dicarbonyl)bis(azanediyl))diisophthalate), was synthesized with thiophenamide-containing tetracarboxylic acid and characterized by elemental analysis, IR spectroscopy, single-crystal diffraction, powder X-ray diffraction, and thermogravimetric analysis. X-ray results showed that each Cd(II) ion was connected to four TDBAT4– to form a 3D framework, and the charge balance of the framework was kept by dimethylamine cations. The 3D framework interpenetrated each other to form a 3D + 3D → 3D framework. Due to the anionic framework and luminescence property of 1, the dye adsorption behavior toward cationic methylene blue (MB) and luminescence sensing property toward the nitroaromatic compounds (NACs) were evaluated. The compound adsorbed the high amount (1004.12 mg g–1) of MB and could separate MB from the MB/MO mixture. Moreover, the compound displayed the detections for hydroxyl-substituted NACs (4-nitrophenol, 2,4-dinitrophenol and 2,4,6-trinitrophenol) with detection limits of 8.14, 11.85, and 5.7 ppm, respectively, in the presence of interfering compounds. The adsorption ability of 1 toward cationic dye was assigned to predominantly electrostatic interaction and ion exchange. The possible detection mechanism for hydroxyl-substituted NACs could be attributed to competitive light absorption and hydrogen bonding interactions. The compound displayed reusability for MB adsorption and detection of hydroxyl-substituted NACs.
