The reduction of silver cations bound to the oligonucleotide dC(12) was used to form silver nanoclusters. Mass spectra show that the oligonucleotides have 2-7 silver atoms that form multiple species,… (More)
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. The photophysics… (More)
The fluorescence of silver clusters encapsulated by single stranded oligo-DNA (24 cytosine base pairs, C(24):Ag(n)) was used to monitor the transfection of this new silver/DNA fluorophore inside… (More)
Small silver nanoclusters are synthesized using polycytosines as matrices. Different size silver nanoclusters ranging from Ag1 to Ag7 exhibit bright emission maxima at blue (480nm), green (525nm),… (More)
Aqueous bromine atoms were produced by laser flash photolysis of 1,2-dibromoethane at 248 nm in solutions containing bromide ions. Forward and reverse rate constants of the title reaction were… (More)
