چکیده

We report the discovery of a DNA sequence that templates a highly stable fluorescent silver nanocluster. In contrast to other DNA templated silver nanoclusters that have a relatively short shelf-life, the fluorescent species templated in this new DNA sequence retains significant fluorescence for at least a year. Moreover, this new silver nanocluster possesses low cellular toxicity and enhanced thermal, oxidative, and chemical stability.

Ag K-edge EXAFS analysis of DNA-templated fluorescent silver nanoclusters: insight into the structural origins of emission tuning by DNA sequence variations.

DNA-templated silver nanoclusters are promising biological fluorescence probes due to their useful fluorescence properties, including tunability of emission wavelength through DNA template sequence variations. Ag K-edge EXAFS analysis of DNA-templated silver nanoclusters has been used to obtain insight into silver nanocluster bonding, size, and structural correlations to fluorescence. The resul...

Silver nanocluster aptamers: in situ generation of intrinsically fluorescent recognition ligands for protein detection.

We have synthesized an intrinsically fluorescent recognition ligand that combines the high fluorescence quantum yield (>50%) of oligonucleotide templated AgNCs with the specificity and strong binding affinity of DNA aptamers for their target proteins, to develop a new strategy for detection of specific proteins.

Modulating DNA-templated silver nanoclusters for fluorescence turn-on detection of thiol compounds.

Based on the fact that the fluorescence response pattern of a silver nanocluster to a specific analyte is highly dependent on the nature of the DNA template, we develop a novel fluorescence turn-on assay for thiol compounds with high specificity and sensitivity by modulating DNA-templated silver nanoclusters.

A nanocluster beacon based on the template transformation of DNA-templated silver nanoclusters.

In this work, we developed a novel light-up nanocluster beacon (NCB) based on shuttling dark silver nanoclusters (NCs) to a bright scaffold through hybridization. The fluorescence enhancement was as high as 70-fold when the two templates were on the opposite sides of the duplexes, enabling sensitive and selective detection of DNA.

DNA/RNA Detection Using DNA-Templated Few-Atom Silver Nanoclusters

DNA-templated few-atom silver nanoclusters (DNA/Ag NCs) are a new class of organic/inorganic composite nanomaterials whose fluorescence emission can be tuned throughout the visible and near-IR range by simply programming the template sequences. Compared to organic dyes, DNA/Ag NCs can be brighter and more photostable. Compared to quantum dots, DNA/Ag NCs are smaller, less prone to blinking on l...
