Abstract:

Highly luminescent BSA-gold clusters were synthesized and its polymer composites were prepared using PVA, PVP and PVA/PVP blend. UV-visible spectroscopy, Photoluminescence, Fourier transform infrared spectroscopy (FTIR), Transmission electron microscopy (TEM) and particle size analysis (DLS) were performed to determine the formation of gold clusters. Luminescence properties of BSA-Gold cluster and its polymer composites were evaluated and it is found that all polymers quench the fluorescence at 650 nm while PVP and PVP/PVA blend enhance the fluorescence at 450 nm. Further, a Surface Plasmon Re

Abstract:

Owing to aurophilic interactions, linear and/or planar Au(I)-thiolate molecules spontaneously aggregate, leading to molecular gold clusters passivated by a thiolate monolayer coating. Differently from the thiolate precursors, such cluster compounds show very intensive visible fluorescence characteristics that can be tuned by alloying the gold clusters with silver atoms or by conjugating the electronic structure of the metallic core with unsaturated electronic structures in the organic ligand through the sulphur atom. Here, the photoluminescence features of some examples of these systems are sh

Abstract:

Highly fluorescent Au /polystyrene nanocomposite films have been prepared by thermal decomposition at 250°C of gold mercaptide molecules (dodecyl-mercaptide of gold(I), C 12 H 25 SAu ) dissolved in polystyrene. Owing to a continuous nucleation of metallic phase generated by the thermolysis reaction, molecular gold clusters, which are characterized by fluorescence properties because of the very small size, can be obtained by this very simple technique.

Abstract:

Fluorescent gold nanoclusters (AuNCs) have been extensively studied due to their unique construction and distinctive properties, which place them between single metal atoms and larger nanoparticles. The dimension of AuNCs is comparable to the Fermi wavelength of electrons, which lead to size-dependent fluorescence and other molecule-like properties. In this review, we summarize various synthesis strategies of fluorescent AuNCs and recent advances of biological applications such as biosensing, biolabeling, and bioimaging. The synthetic methods are considered as two routes: “Atoms to Clusters” a

Abstract:

Atomically precise metal clusters have attracted increasing interest owing to their unique size-dependent properties; however, little has been known about the effect of size on the catalytic properties of metal clusters at the single-cluster level. Here, by real-time monitoring with single-molecule fluorescence microscopy the size-dependent catalytic process of individual Au clusters at single-turnover resolution, we study the size-dependent catalytic behaviors of gold (Au) clusters at the single-cluster level, and then observe the strong size effect on the catalytic properties of individual A
