Abstract Metal-organic frameworks (MOF) are an extraordinarily versatile class of porous nanostructured materials that have gained popularity in several scientific fields. Organic ligands coupled to the inorganic metal centers or clusters produce MOFs.

Various techniques, such as cyclic voltammetry (CV), chronoamperometry, differential pulse (DPV) been employed enhance sensitivity specificity. EC sensing systems hold promise medical diagnostics, particularly diseases diabetes, neurodegenerative cardiovascular disorders, cancer. These sensors offer distinctive features like extensive specific surface area, tunable pore sizes, exceptional catalytic performance, abundant active sites, enabling sensitive, rapid, cost-effective biomarker detection. The construction different nanostructures, nanoparticles, nanorods, nanowires, three-dimensional networks, has further improved electro-catalytic efficiency materials. We also assess performance advanced MOF-derived sensor platforms, discuss future challenges potential improvements, enzyme-free clinical diagnostics. work underscores effective tools detecting a wide range compounds biomolecules relevant human health.

ABSTRACT One‐dimensional coordination polymer La‐CP , {[La(H 2 O) (HL O ) (L )]·H O} n containing a new luminescent ligand 4,7‐di(4‐carboxypyrazol‐1‐yl)‐2,1,3‐benzoxadiazole (H L was synthesized. Upon excitation at 400 nm, the compound shows strong emission with maximum 550 nm high photoluminescence quantum yield of 43%. demonstrates sensing properties toward aluminum and gallium cations, as well dihydrogen phosphate sulfate anions through enhancement response. The limits detection were 0.42, 0.70, 0.37, 0.40 μM, respectively. is first example sensor for anion among all types polymers. uptake analytes under conditions evaluated, absorption result such proposed probable response mechanism.

This study successfully developed a new dual-mode sensor material based on the nickel metal-organic framework (Ni-MOF) [Ni(tatrz)1.5(5-MIA)·H2O] (CUST-986) (tatrz = 1-(9-(1H-1,2,4-triazol-1-yl)anthracen-10-yl)-1H-1,2,4-triazole, 5-MIA 5-methylisophthalic acid, CUST Changchun University of Science and Technology) for highly efficient detection 2,4,6-trinitrophenol (TNP). In fluorescence sensing mode, CUST-986 demonstrates exceptional selective recognition capability TNP, with high quenching constant (Ksv) 1.676 × 105 M-1 an ultralow limit (LOD) 69.3 nM. electrochemical modified electrode achieves TNP 0.48 μM. Real environmental sample tests show spike recovery rates 80.3-93.6%, indicating good potential practical applications long-term stability. Through characterization techniques including powder X-ray diffraction, UV-vis, DFT calculations, lifetime measurements, mechanism electron transfer inner filter effect was elucidated. bifunctional MOF provides solution monitoring public safety applications.
