A luminescent Eu3+-functionalized MOF for sensitive and rapid detection of tetracycline antibiotics in swine wastewater and pig kidney

Detection Enhancement of One Multifunctional Cd-Metal–Organic Framework toward Tetracycline Antibiotics by Simply Mixing Eu3+ in Suspension

“…34,62−69 low detection limit of 0.118 μM toward OTC. 34 Simple mixing of Ln 3+ in suspensions with MOF as the chemisensor, to the best of our knowledge, has never been reported before. All above results demonstrated that Eu 3+ @LCU-117 possessed excellent potential in OTC sensing applications.…”

“…The detection limit values of LCU-117 toward OTC whether Eu 3+ was present or not are similar to those of recently reported samples (Table S4). − Time-dependent luminescence has been performed on the Eu 3+ @LCU-117 toward OTC (Figure c). Based on the result, all sensing activities showed fast response within 20 s. As far as we know, Ln 3+ post-modified MOF materials have generally been employed for chemisensors to detect antibiotics or other chemicals. ,− For example, very recently, He’s group reported one Eu 3+ -functionalized MOF named EuUCBA to detect TCs through luminescence quenching, which showed a low detection limit of 0.118 μM toward OTC .…”

“…Tetracycline antibiotics (TCs), the second group of antibiotics consumed worldwide, including tetracycline (TC), chlortetracycline (CTC), and oxytetracycline (OTC), have been widely prescribed for animal and human use because of their broad antibacterial and growth-promoting effects in aquaculture . Some MOFs have been explored to detect TCs. − Discriminative detection among this kind of antibiotics, however, is still challenging.…”

Hydrogen bonding-mediated assembly of carbon dot@Zr-based metal organic framework as a multifunctional fluorescence sensor for chlortetracycline, pH and temperature detection

“…Based on the linear fluorescence response behaviors of CDs@UiO-66(COOH) 2 -50 toward CTC containing aqueous solution, the detection limit was calculated to be 0.102 μM at a signal-to-noise ratio of 3. Compared to most of the related fluorescence CTC sensors reported previously using another synthetic method, 40–44 the solvent-free synthesis of the CDs@UiO-66(COOH) 2 -50 sensor showed a much lower LOD value in a wider linearly response range (Table 1).…”

Full Green Detection of Antibiotic Tetracyclines Using Fluorescent Poly(ethylene glycol) as the Sensor and the Mechanism Study

“…However, the broad use of these antibiotics has led to their ubiquitous presence in the environment, making them persistent organic contaminants, and the chronic environmental risk of their exposure has been gaining more attention. − Therefore, their monitoring and detection have been in high demand, and different techniques have been developed to this end, including, for example, classical spectrophotometry, electrochemical analysis, − HPLC, , molecular imprinted polymers (MIP), ,− capillary electrophoresis analysis, etc. − Abreast with these methodologies, chemiluminometry, or simply fluorometry, has been also developed and is gaining more and more importance − owing to the easy operation and high reliability of the advanced instruments. Nevertheless, it should be noted that, among all reported fluorometric determinations to date, the preparation of the sensors involves, in general, cancerous or hazardous compounds, − transition metals, ,− and either their MOFs, quantum dots, or composites ,,,− and requires sophisticated multistep processes ,,,,− and even high-cost rare-earth materials. , Regardless of these issues, a constant and rapid growth has been seen for monitoring and detection of tetracycline antibiotics since the last few decades.…”
