Journal ArticleDOI
Luminescent Ag7 and Ag8 Clusters by Interfacial Synthesis
TL;DR: Gram-scale syntheses of two luminescent silver clusters, protected by small molecules containing thiol groups, with well-defined molecular formulas, by interfacial synthesis are presented, promising in several other areas including semiconductor nanoparticles, two-dimensional superlattices, and 3D structures.
Journal ArticleDOI
Ligand Exchange of Au25SG18 Leading to Functionalized Gold Clusters: Spectroscopy, Kinetics, and Luminescence
TL;DR: In this paper, a ligand exchange was used to tune optical and photoluminescence properties of one of the most stable quantum clusters of gold, Au25SG18 (SG-glutathione thiolate), functionalized by the exchange of −SG with functionalized -SG and with an altogether different ligand, namely, 3-mercapto-2-butanol (MB).
Journal ArticleDOI
Copper quantum clusters in protein matrix: potential sensor of Pb2+ ion.
Nirmal Goswami,Anupam Giri,Megalamane S. Bootharaju,Paulrajpillai Lourdu Xavier,Thalappil Pradeep,Samir Kumar Pal +5 more
TL;DR: The quenching of luminescence of the protein-capped Cu QCs in the presence of very low hydrogen peroxide concentration reflects the efficacy of the QCs as a potential sensing material in biological environments.
Journal ArticleDOI
Molecular-receptor-specific, non-toxic, near-infrared-emitting Au cluster-protein nanoconjugates for targeted cancer imaging
Archana Retnakumari,Sonali Setua,Deepthy Menon,Prasanth Ravindran,Habeeb Muhammed,Thalappil Pradeep,Shantikumar V. Nair,Manzoor Koyakutty +7 more
TL;DR: Receptor-targeted cancer detection using Au clusters is demonstrated on FR(+ve) oral squamous cell carcinoma (KB) and breast adenocarcinoma cell MCF-7, where the FA-conjugated Au(25) clusters were found internalized in significantly higher concentrations compared to the negative control cell lines.
Journal ArticleDOI
Picosecond optical nonlinearity in monolayer-protected gold, silver, and gold-silver alloy nanoclusters
TL;DR: In this paper, a monolayer-protected Au, Ag, and Au:Ag alloy nanoclusters have been synthesized using octanethiol and octadecanethiol as capping agents.
