Two luminescent phosphonate metal-organic framework as highly efficient and sensitive sensors for the detections of tetracycline antibiotic in aqueous system

A Europium Metal–Organic Framework and Its Polymer Composite Membrane as Switch-Off Fluorescence Sensors for Antibiotic Detection in Lake Water

“…A summarized comparison of Eu-DPOE with other reported MOF-based antibiotic fluorescence sensors is listed (Supporting Information, Table S1). By comparing LODs of Eu-DPOE to those of the presented antibiotics, we can find that LODs of Eu-DPOE are comparable to or better than most reported fluorescence sensors in the table, such as EuUCBA (EuUCBA = Eu@UiO-66-(COOH) 2 /p-CBA (0.228 μM), TPE@CLMOF (0.16 μM, TPE = tetraphenylethylene, CLMOF = cyclodextrin cross-linked MOF), In-sbdc (0.30 μM, sbdc 2– = trans-4,4′-stilbenedicarboxylate), and CDs@UiO-66­(COOH) 2 -50 (0.102 μM, CDs = O -phenylenediamine), but higher than those nM-level sensors of 2­[Zn 2 ·L·(H 2 O) 2 ] (2.17 nM) and 2­[Cd­(H 2 L)­(H 2 O) 2 ] (2.69 nM, H 4 L = 5-methyl-1,3-[(phosphonomethyl)­phenyl] methylphosphonic acid) . For convenience, the plots of LOD vs K SV for CTC, NFT, and NOR detections are depicted in Figure a–c.…”

Zinc(II)-MOF: A Versatile Luminescent Sensor for Selective Molecular Recognition of Flame Retardants and Antibiotics

“…On the other hand, pharmaceutical antibiotics are usually used against infections in humans, animals, and plants. Yet, their transformation products stand out as a conspicuous category of environmental pollutants because of their poor metabolism and absorption by humans and animals resulting in the development of antibiotic-resistant bacteria and antibiotic-resistant genes over the long term, showcasing profound impacts on the ecosystem. − Tetracyclines (TCs) stand out as a unique class of antibiotics with a wide-ranging antibacterial effect, commonly employed in treating infections of the urinary and respiratory tracts. , However, prolonged exposure to TCs may lead to severe health issues, such as tooth discoloration, skin photosensitization, and liver damage. − Likewise, nitroimidazole-based antibiotics play crucial roles in improving public health and fostering the growth and development of livestock. Nevertheless, the ease of residue accumulation and the challenging degradation of these antibiotics have led to detrimental water and soil contaminations, posing risks to food safety, and presenting significant threats to human health. , Therefore, it is necessary and urgent need of the hour to explore an effective method for detecting the TCs and 5-nitroimidazole-based antibiotics to prevent human health as well as the environment. , …”
