Correlation of photobleaching, oxidation and metal induced fluorescence quenching of DNA-templated silver nanoclusters
Morishita, Kiyoshi; MacLean, James L.; Liu, Biwu; Jiang, Hui; Liu, Juewen (Royal Society of Chemistry, 2013-04-07)Few-atom noble metal nanoclusters have attracted a lot of interest due to their potential applications in biosensor development, imaging and catalysis. DNA-templated silver nanoclusters (AgNCs) are of particular interest ... -
DNA stabilized silver nanoclusters for ratiometric and visual detection of Hg2+ and its immobilization in hydrogels
MacLean, James L.; Morishita, Kiyoshi; Liu, Juewen (Elsevier, 2013-04-11)DNA oligomers are particularly interesting templates for making silver nanoclusters (AgNCs) as different emission colors can be obtained by varying the DNA sequence. Many AgNCs have been used as Hg2+ sensors since Hg2+ ... -
Nucleotide coordination with 14 lanthanides studied by isothermal titration calorimetry
Zhang, Zijie; Morishita, Kiyoshi; Lin, Wei Ting David; Huang, Po-Jung Jimmy; Liu, Juewen (Elsevier, 2017-06-09)With their hydrolytic, optical and magnetic properties, lanthanide ions (Ln3+) are versatile probes for nucleic acids. In addition, nucleotide-coordinated Ln3+ ions form useful nanoparticles. However, the thermodynamic ... -
Towards understanding of poly-guanine activated fluorescent silver nanoclusters
Walczak, Sylwia; Morishita, Kiyoshi; Ahmed, Moin; Liu, Juewen (Institute of Physics, 2014-03-18)It has been recently reported that the fluorescence of some DNA-templated silver nanoclusters (AgNCs) can be significantly enhanced upon by hybridizing with a partially complementary DNA containing a G-rich overhang near ...
