Rapid detection of the 3-nitrotyrosine (3-NT) biomarker in serum is great significance clinical diagnosis and daily disease monitoring. In this work, two chemorobust 3D metal–organic frameworks (MOFs) [Co(DBrTPA)(NMP)]n (CoMOF-1) [Co5(DBrTPA)4(DMF)6(HCOO)2]n (CoMOF-2) were fabricated from a halogen-modified ligand 2,5-dibromoterephthalic (H2DBrTPA) cobalt(II) clusters under solvothermal conditions. The introduction halogens can improve stability overall framework different media pH environments, which also endow CoMOFs with potential as luminescent sensors high sensitivity selectivity, fast response, good anti-interference, well recyclable performance detecting 3-NT PBS buffer solution through quenching effects, Ksv values being 9.19 × 104 M–1 for CoMOF-1 1.05 105 CoMOF-2 LODs low 23.6 ng·mL–1 20.1 CoMOF-2. Furthermore, developed employed to quantify real samples, satisfactory results. addition, possible sensing mechanisms toward discussed photoinduced electron transfer spectral overlaps. This work demonstrated excellent MOF-based provided an outlook design help artificial intelligence machine learning.

Anionic, acidic, and metal ions are common contaminants in water cause serious concerns for human aquatic life. With the goal of rapid detection analytes, we herein design a new array ligand 5-(4H-1,2,4-triazol-4-yl)pyridin-3-ol-linked silver coordinated metal-organic frameworks Ag-MOFs as promising sensor Cr2O72-, MnO4-, humic acid (HA), Fe3+ down to micro level. Furthermore, evidenced by luminescence, excitation-emission matrix (EEM) spectroscopic, PXRD measurements, designed (MOFs) can be fast, stable, reusable analyte water.

Metal-organic frameworks (MOFs) are novel inorganic-organic hybridized crystals with a wide range of applications. In the last twenty years, fluorescence sensing based on MOFs has attracted much attention. can exhibit luminescence from metal nodes, ligands or introduced guests, which provides an excellent response in sensing. However, single-signal emitting susceptible to interference concentration, environment, and excitation intensity, resulting poor accuracy. To overcome shortcomings, dual-emission MOF-based ratiometric sensors have been proposed rapidly developed. this review, we first introduce mechanisms, synthetic methods, detection mechanisms MOFs, highlight strategies for constructing classify them into three categories: intrinsic single-emission luminescent non-emission other materials. Then, summarize recent advances various analytical industries. Finally, discuss current challenges prospects future development these sensors.
