Journal ArticleDOI
DNA-templated Ag nanocluster formation.
TL;DR: Fluorescence, absorption, mass, and NMR spectra all indicate that multiple species are present, but that their creation is both nucleotide- and time-dependent, and that the nanoclusters are associated with the chiral ss-DNA template.
Journal ArticleDOI
High quantum yield blue emission from water-soluble Au8 nanodots
TL;DR: These easily prepared, water-soluble, and high quantum yield gold nanodots lend insight into the molecular nature of small metal nanoclusters and may find application as novel biocompatible fluorophores.
Journal ArticleDOI
Ag Nanocluster Formation Using a Cytosine Oligonucleotide Template.
Caroline M. Ritchie,Kenneth R. Johnsen,John R. Kiser,Yasuko Antoku,Robert M. Dickson,Jeffrey T. Petty +5 more
TL;DR: Mass spectra show that the oligonucleotides have 2-7 silver atoms that form multiple species, as evident from the number of transitions in the fluorescence and absorption spectra, and the formation of oxidized nanoclusters is proposed.
Journal ArticleDOI
Base-Directed Formation of Fluorescent Silver Clusters
Bidisha Sengupta,Caroline M. Ritchie,Jenna G. Buckman,Kenneth R. Johnsen,Peter M. Goodwin,Jeffrey T. Petty +5 more
TL;DR: The results suggest that cytosine- and thymine-containing oligonucleotides stabilize a preferred emissive silver cluster.
Journal ArticleDOI
DNA Encapsulation of Ten Silver Atoms Produces a Bright, Modulatable, Near Infrared-Emitting Cluster.
Jeffrey T. Petty,Chaoyang Fan,Sandra P. Story,Bidisha Sengupta,Ashlee St. John Iyer,Zachary D. Prudowsky,Robert M. Dickson +6 more
TL;DR: The coupled increase in total fluorescence demonstrates that enhanced sensitivity can be realized through Synchronously Amplified Fluorescence Image Recovery (SAFIRe), which further differentiates this new fluorophore.
