Polarization properties of fluorescent BSA protected Au25 nanoclusters.
BSA protected gold nanoclusters (Au25) are attracting a great deal of attention due to their unique spectroscopic properties and possible use in biophysical applications. Although there are reports on synthetic strategies, spectroscopy and applications, little is known about their polarization behavior. In this study, we synthesized the BSA protected Au25 nanoclusters and studied their steady s...
متن کاملResonance energy transfer between fluorescent BSA protected Au nanoclusters and organic fluorophores.
Bovine serum albumin (BSA) protected nanoclusters (Au and Ag) represent a group of nanomaterials that holds great promise in biophysical applications due to their unique fluorescence properties and lack of toxicity. These metal nanoclusters have utility in a variety of disciplines including catalysis, biosensing, photonics, imaging and molecular electronics. However, they suffer from several di...
متن کاملRemarkable enhancement in ligand-exchange reactivity of thiolate-protected Au25 nanoclusters by single Pd atom doping.
The effect of Pd doping on the ligand-exchange reactivity of Au(25)(SC(12)H(25))(18) was studied by comparing the ligand-exchange reactivity of [Au(25)(SC(12)H(25))(18)](-) and [PdAu(24)(SC(12)H(25))(18)](0) and the results clearly demonstrate that, regardless of the kind of incoming thiols and solvents, Pd doping greatly increases the rate of ligand exchange of Au(25)(SC(12)H(25))(18), indicat...
متن کاملReversible Photoisomerization of Spiropyran on the Surfaces of Au25 Nanoclusters.
Au25 nanoclusters functionalized with a spiropyran molecular switch are synthesized via a ligand-exchange reaction at low temperature. The resulting nanoclusters are characterized by optical and NMR spectroscopies as well as by mass spectrometry. Spiropyran bound to nanoclusters isomerizes in a reversible fashion when exposed to UV and visible light, and its properties are similar to those of f...
متن کاملModeling the photosensitizing properties of thiolate-protected gold nanoclusters.
An accurate computational strategy for studying the structural, redox and optical properties of thiolated gold nanoclusters (GNCs) using (Time-Dependent) Density Functional Theory is proposed. The influence of the pseudopotential/basis set, solvent description and the choice of the functional has been investigated to model the structural and electronic properties of the Au25(SR)18(-) system, wi...
