The widespread use of herbicides like dinitro--cresol (DNOC) and veterinary drugs such as furaltadone (FLT) has surged to meet agricultural and animal husbandry demands, raising significant health and environmental concerns due to their extensive use and unregulated disposal. To address this issue, herein, we developed an imidazole-functionalized metal-organic framework (MOF)-based fluorometric dual sensor for rapid and selective detection of these analytes in aqueous medium. The present MOF-based probe demonstrated 82% fluorescence quenching upon DNOC introduction, whereas 89% quenching occurred in the presence of FLT.

Nitrofuran antibiotics (NFAs) residues in waterare a persistent concern for the public due to the potential threats they pose to human health and the environment. Therefore, efficient probes that are capable of detecting trace amounts of antibiotics in real water environments have become a top priority. Herein, a novel fluorescent Zn-MOF probe (MOF-1) was revealed for the highly selective and sensitive sensing of NFAs.

The misuse of antibiotics has caused serious impacts on food safety and human health, making it crucial to develop rapidly and highly sensitive methods for detecting trace nitrofuran antibiotics (NFs). In this study, phosphorus, nitride-doped carbon nanosheets (PN/CNs) were synthesized using a simple hydrothermal method based on graphitic carbon nitride. This prepared material showed excellent water solubility and stable optical properties.

Nitrofurans are important synthetic broad-spectrum antibacterial drugs with the basic structure of 5-nitrofuran. Due to their toxicity, it is essential to develop a sensitive sensor with strong anti-interference capabilities for their detection. In this work, two {PMoO}-based compounds, [H(HPTTP)]{Cu[MoO(OH)(PO)(HPO)(HPO)]}·HO ( = 13 for (), 7 for (); HPTTP = 4,4',4″,4‴-(1-pyrrole-2,3,4,5-tetrayl)tetrapyridine), exhibiting similar coordination but distinct stacking modes.

Because the accurate and rapid detection of antibiotics and pH plays an important role in biological systems and environmental fields, developing suitable and efficient sensors that can simultaneously detect antibiotics and pH has become important. In this work, we successfully designed and synthesized two new one-dimensional coordination polymers based on the mixed ligands L [,'-bis(4-methylpyridin-4-yl)-2,6-naphthalene dicarboxylamide] and HCPG [3-(4-chlorophenyl)glutaric acid], [M(L)(HCPG)(HO)] (M = Co for CP , and M = Ni for CP ), which were structurally characterized by single-crystal X-ray diffraction, infrared spectroscopy, powder X-ray diffraction, and thermogravimetric analysis. CP and CP can be used as ultraversatile fluorescent sensors, which can sense erythromycin (ERY) and oxacillin (OXC) by turn-on fluorescent enhancement and detect furaltadone (FTD) via the turn-off fluorescent quenching effect, separately.
