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
Protein-flavonol interaction: fluorescence spectroscopic study.
TL;DR: Analysis of relevant spectroscopic data leads to the conclusions that two binding sites are involved in BSA–3HF interaction, and the interaction is slightly positively cooperative in nature with a similar binding constant.
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.
Journal ArticleDOI
DNA Templates for Fluorescent Silver Clusters and I-Motif Folding
Bidisha Sengupta,Kerianne Springer,Jenna G. Buckman,Sandra P. Story,Oluwamuyiwa Henry Abe,Zahiyah W. Hasan,Zachary D. Prudowsky,Sheldon E. Rudisill,Natalya N. Degtyareva,Jeffrey T. Petty +9 more
TL;DR: When assessed by size exclusion chromatography, the oligonucleotide and cluster conjugate have similar global structures, which indicate that the DNA strands are similarly organized at this pH.
Journal ArticleDOI
Optically Enhanced, Near-IR, Silver Cluster Emission Altered by Single Base Changes in the DNA Template
Jeffrey T. Petty,Chaoyang Fan,Sandra P. Story,Bidisha Sengupta,Matthew M. Sartin,Jung-Cheng Hsiang,Joseph W. Perry,Robert M. Dickson +7 more
TL;DR: These studies of optically gated fluorescence bolster the critical role of the nucleobases in both the formation and excited state dynamics of these highly emissive metallic clusters.
