ABSTRACT We developed a novel strategy to prepare functionalized fluorescent gold nanodots (AuNDs) based on a ligand exchange reaction and demonstrated that glutathione modified AuNDs can be utilized for highly sensitive and selective Pb(2+) sensing in aqueous solution.

    ABSTRACT: Fluorescent silver nanoclusters, in particular DNA stabilized (templated) silver nanoclusters, have attracted much attention because of their molecule-like optical properties, strong fluorescence and good biocompatibility. In this feature article, we summarize the DNA stabilized silver nanoclusters from the viewpoints of synthesis, optical properties, as well as recent applications in biological detection and imaging.

    ABSTRACT: In this paper, an aqueous-based route has been developed to prepare highly luminescent glutathione (GSH)-capped Mn-doped ZnS quantum dots (QDs). The dots obtained have an average diameter of 4.3 nm and exhibit the Mn2+-related orange luminescence with very low surface defect density. The highest photoluminescence was observed for a Mn2+ to Zn2+ molar ratio of 3%. Consecutive overcoating of the Mn:ZnS@GSH QDs by a ZnS shell was done, and the core/shell structured QDs exhibit a PL quantum yield of 23%. Transmission electron microscopy, X-ray powder diffraction, electron spin resonance, X-ray photoelectron spectroscopy, UV–visible spectroscopy and spectrofluorometry have been used to characterize the crystal structure, the doping status, and the optical properties of the doped-QDs. Our systematic investigation shows that Mn:ZnS/ZnS@GSH QDs are highly promising fluorescent labels in biological applications.

    ABSTRACT: Synthesis and characterization of gold nanoclusters (Au NCs) stabilized by a zwitterion ligand (Zw) at different Au : Zw ratios are demonstrated. Au NCs exhibit photoluminescence (PL) emission which is tunable from the near infrared (805 nm) to the red spectral window (640 nm) and strongly influenced by the ligand shell size. Optical and chemical investigations suggest the presence of gold polymeric species and large nanoclusters for a molar ratio of Au : Zw = 1 : 1. For 1 : 5 < Au : Zw < 1 : 1, Zw induces etching of the large clusters and the formation of a monolayer of the bidentate ligands on the Au NCs (cluster size ∼7 to 10 kDa) accompanied by red PL emission at λ = 710 nm. A second organic layer starts to form for larger Zw fractions (Au : Zw < 1 : 5) as a result of electrostatic and covalent interactions of the zwitterion leading to an enhancement and a blue-shift of the PL emission. The effect of temperature and pH on the optical properties of gold clusters is strongly dependent on the ligand shell and demonstrates the importance of defining gold nanoclusters as supramolecular assemblies with a complex environment.
