Silver nanoclusters are bright, stable and well suited for single-molecule applications. 
Fluorescent silver nanoclusters.
TLDR
The different scaffolds that are used as stabilizer for silver nanoclusters (e.g. polymers, dendrimers, DNA oligomers, cryogenic noble gas matrixes, inorganic glasses, zeolites and nanoparticles) are overviewed. Expand
Blue, green and red emissive silver nanoclusters formed in organic solvents.
Strongly luminescent silver nanoclusters with tunable emission are directly synthesized in organic polar and apolar solvents. We show that an amphiphilic polystyrene-block-poly(methacrylic acid)Expand
DNA-templated fluorescent silver nanoclusters
TLDR
Various oligonucleotide sequences or conformations have been utilized to synthesize silver nanoclusters with excellent fluorescence properties, and the range of applications has expanded greatly, from live cell staining and the detection of metal ions and small biomolecules to the Detection of DNA or proteins.

Few-Atom Silver Clusters as Fluorescent Reporters
Silver clusters, composed of only a few silver atoms, have remarkable optical properties based on electronic transitions between quantized energy levels. They have large absorption coefficients andExpand
An atomically precise all-tert-butylethynide-protected Ag51 superatom nanocluster with color tunability.
TLDR
Ag51 exhibits a strong solvatochromic effect, and the emissions are strongly dependent on the solvent polarity and are tunable from blue to red by changing the solvent from less polar dichloromethane to highly polar methanol. Expand

Silver clusters, composed of only a few silver atoms, have remarkable optical properties based on electronic transitions between quantized energy levels. They have large absorption coefficients andExpand
Cell-Specific Aptamers for Molecular Imaging
Aptamers, single-stranded oligonucleotides, are an important class of molecular targeting ligands. Since their discovery, aptamers have been rapidly translated into bioanalytical practice. They haveExpand
A "light-up" and "spectrum-shift" response of aptamer-functionalized silver nanoclusters for intracellular mRNA imaging.
TLDR
A novel multifunctional DNA scaffold for the synthesis of fluorescent silver nanoclusters (Ag NCs) using a one-pot approach presented a "light-up" and "spectrum-shift" response to target DNA in vitro and could further image the tumor-related mRNA in living cells. Expand
Sub-microwatt direct laser writing of fluorescent gold nanoclusters in polymer films
We report on the micro-pattering of fluorescent gold nanoclusters embedded in polyvinyl alcohol film using a low-cost continuous-wave laser. We show that the formation of gold nanoclusters requiresExpand
Metal nanoclusters: New fluorescent probes for sensors and bioimaging
Summary Fluorescent metal nanoclusters (NCs) as a new class of fluorophores have attracted more and more attention due to their unique electronic structures and the subsequent unusual physical andExpand

Strongly emissive individual DNA-encapsulated Ag nanoclusters as single-molecule fluorophores
TLDR
The water-soluble, near-IR-emitting DNA-encapsulated silver nanocluster presented herein exhibits extremely bright and photostable emission on the single-molecule and bulk levels, and the nonpower law blinking kinetics suggest that these very small species may be alternatives to much larger and strongly intermittent semiconductor quantum dots.
