“…In addition, previous studies on the detection of NFZ were summarized. − As shown in Table S2, this work provides a low detection limit and high detection sensitivity, and the operation is simple, fast, and feasible. Therefore, 1 can be deemed as a unique bi-functional sensing platform for FA and NFZ.…”

Metal−organic frameworks (MOFs) are a kind of nanoporous coordination materials, which have the advantages of high crystallinity and tunable functionalization. Carbon dots (CDs) are zerodimensional luminescent carbon nanomaterials, which combine the advantages of small organic molecules such as fluorophores and conventional semiconductors such as inorganic quantum dots. Chiral quantum dots are appealing for detection of chiral substances due to their unique chirality. In this work, chiral CDs can be loaded into zeolitic imidazolate framework-8 (ZIF-8) via an in situ encapsulation method, forming the chiral composite hybrid material CCQDs/ZIF-8 (1). The framework structure and luminescent property of 1 can be maintained after being soaked in water and ethanol for 24 h as confirmed by PXRD characterization. A luminescent experiment demonstrated that 1 can be utilized as a highly sensitive and selective "turn-on" fluorescent probe of Dfolic acid (K BH 9.82 × 10 4 M −1 and detection limit 0.31 μM) and L-folic acid (K BH 2.99 × 10 4 M −1 and detection limit 4.36 μM). 1 also shows good cycling detection performance for D-folic acid (94.96%) and L-folic acid (93.69%). Enantioselective identification between D-folic acid and L-folic acid (K D /K L = 3.28) can be carried out. Furthermore, simultaneously, 1 can be used as an efficient turn-on fluorescence probe to detect the antibiotic nitrofurazone (NFZ; K BH 3.29 × 10 4 M −1 and detection limit 3.06 μM). Further, 1 can be utilized to detect folic acid and NFZ in real samples. The results demonstrated that 1 can be used as a highly efficient turnon detection platform for folic acid and NFZ. Further, 1 with these targeted objects can be successfully applied as a fluorescent ink; a mixed-matrix membrane based on 1 has been prepared. The detection mechanism of composite material 1 for recognition of folic acid and NFZ is also investigated and discussed.

“…Besides, antibiotics are a class of drugs commonly used in animal husbandry, agriculture, and medicine. − Among them, nitrofurazone (NFZ) and nitrofurantoin (NFT) are drugs used for the treatment of bacterial infections. However, misuse of antibiotics leads to high levels of residues that are harmful to human health. ,, Currently, methods for the detection of Gsp in cottonseed and antibiotic residues include UV–visible spectrometry (UV–vis), high-performance liquid chromatography (HPLC), , Fourier transform infrared spectroscopy (FTIR) and near-infrared spectroscopy (NIR), and so forth. Compared with these methods, UV visual colorimetric analysis has great potential for ready-to-use testing due to its convenience, low cost, fast readout, and naked eye recognition. − …”

Gossypol (Gsp) and antibiotics present in water bodies become organic pollutants that are harmful to human health and the ecological environment. Accurate and effective detection of these pollutants has far-reaching significance in many fields. A new three-dimensional metal–organic framework (MOF), {[Eu3(L)2(HCOO–)(H2O)3]·2H2O·2DMF} n (Eu-MOF), was synthesized from 3,5-bis(2,4-dicarboxylphenyl)nitrobenzene (H4L) ligand and Eu3+ via the solvothermal method in this paper. The Eu-MOF demonstrates strong red fluorescence and can remain stable in different pH solutions. The MOF fluorescence probe could detect organic pollutants through the “shut-off” effect, with a fast response speed and a low detection limit [Gsp, nitrofurantoin (NFT), and nitrofurazone (NFZ) for 0.43, 0.38, and 0.41 μM, respectively]. During the testing process, Eu-MOF exhibited good selectivity and recoverability. Furthermore, the mechanism of fluorescence quenching was investigated, and the recoveries were also good in real samples. This paper introduced a deep learning model to recognize the fluorescence images, a portable intelligent logic detector designed for real-time detection of Gsp by logic gate strategy, and an anticounterfeiting mark prepared based on inkjet printing. Importantly, this work provides a new way of thinking for the detection of organic pollutants in water with high sensitivity and practicality by combining the fluorescence probe with machine learning and logical judgment.
