Nanoscale UiO-MOF-based luminescent sensors for highly selective detection of cysteine and glutathione and their application in bioimaging

Abstract

We report a practical approach, the first of its kind, to construct nanoscale UiO-type metal-organic framework (Mi-UiO-66 and Mi-UiO-67) fluorescent probes for the detection of Cys and GSH. They showed high sensitivity (10(-11) M) and selectivity for Cys and GSH, and their fluorescence imaging of Cys and GSH in living cells was well demonstrated.

Facile Synthesis and Characterization of MOF‐Derived Porous Co3O4 Composite for Oxygen Evolution Reaction

“…Metal‐organic framework (MOFs) or coordination polymers (PCPs) have attracted more and more attentions in recent years owing to its unique topology, large specific surface area and porous structure . Due to the original structure and properties, MOFs have a wide applications in gas storage, sensor, heterogeneous catalysis, separation, drug delivery, light, electricity, magnetism and so on. MOFs also can be applied as self‐sacrificial templates or precursors to construct novel nanostructure with various morphologies.…”

Advanced Porous Materials in Mixed Matrix Membranes

“…Since its first discovery in 2008, UiO‐66 has attracted much attention in a wide variety of applications, such as catalysis, separation, drug delivery, and bioimaging, mainly due to its high porosity, rich chemical functionality, and most importantly, excellent stability in water and various organic solvents. The original UiO‐66 constructed from Zr 6 (µ 3 ‐O) 4 (µ 3 ‐OH) 4 (COO) 12 clusters and linear dicarboxylate linkers features a face‐centered‐cubic crystal structure.…”

Water-resistant porous coordination polymers for gas separation

“…Conventionally, zeolite and activated carbon materials have been used as the absorbent for impurities removal in mixed gas systems [177,178]. However, PCP materials, especially water stable PCPs, are believed to be the most promising candidates for adsorptive separation.…”

“…As another energy-saving and high efficiency strategy for gas separation, membrane technology has received a great deal of attention in the last few decades [173,176,177,[182][183][184][185]. However, for gas separation, the mechanism of the molecule sieve requires ultra-high standards for the permeated channels of the membrane materials.…”
