Gold nanoclusters encapsulated into zinc-glutamate metal organic frameworks for efficient detection of H₂O₂

Abstract

Gold nanoclusters (AuNCs) have large Stokes shifts and long fluorescence life, which makes them have high application value in bioanalytical applications. However, the quantum yield (QY) of AuNCs was lower,...

Gold nanocluster composites: preparation strategies, optical and catalytic properties, and applications

“…The special porous spatial structure of ZIF not only preserved the biocatalysis of AuNCs, but also prevented macromolecules from entering the framework and interacting with the encapsulated AuNCs. 156 Thus, AuNC composites show better selectivity than bare AuNCs. Furthermore, considering that ZIF is susceptible to oxidative decomposition by H 2 O 2 , this kind of composite is often applied in the detection of H 2 O 2 156 and other substances which generate H 2 O 2 .…”

Luminescent Guests Encapsulated in Metal–Organic Frameworks for Portable Fluorescence Sensor and Visual Detection Applications: A Review

“…Chen and co-workers prepared AuNCs@zinc glutamate MOFs (AuNCs@ZnGlu-MOFs), using a unique one-pot method. Its good optical properties suggest that it could be used as a selective and sensitive fluorescent probe for the detection of H 2 O 2 and H 2 O 2 -related analytes [ 100 ].…”

Origin of luminescence properties and synthetic methods for gold- and bimetallic gold-based nanomaterials

“…58 The most common applications of luminescent gold nanomaterials have been observed in sensing applications by varying their luminescence intensities in the presence of target analytes. Metal ions 59,60 such as Cu 2+ , Hg 2+ , and Fe 3+ , small molecules [61][62][63][64][65][66][67] such as protons, CN À , H 2 O 2 , H 2 S, pyrophosphate, dicofol, and ciprofloxacin, and biomolecules [68][69][70] such as alkaline phosphatase, uric acid, glucose and glucose oxidase are important classes of targets reported since 2021. Another notable detection is the hepatitis B virus through the luminescence properties of AuNCs.…”
