Cysteamine capped silver nanoclusters: A potential antimicrobial agent for antibiotic-resistant bacteria

Fluorescence Resonance Energy Transfer in a Supramolecular Assembly of Luminescent Silver Nanoclusters and a Cucurbit[8]uril-Based Host–Guest System

“…Here, significant changes were observed in the lifetime values of shorter components. In light-emitting metal NCs, the shorter components have been ascribed to the interband transition (d → sp) of metal cores, while the longer lifetime components have been reported to originate from the ligand-to-metal charge-transfer transition. , Interestingly, for this donor–acceptor pair, we obtained CIE coordinates (0.35, 0.31) which resemble pure WLE better than that was observed with the AgHSA NC system as the donor (Figure f). The Förster distance was calculated to be 29.42 Å, and the distance between the donor and acceptor was estimated to be 27.48 Å.…”

pH-Switchable phenylalanine-templated copper nanoclusters: CO2 probing and efficient peroxidase mimicking activity

“…1 MNCs possess discrete electronic energy levels owing to their size, which is comparable to the Fermi wavelength of a conducting electron. 1,2 The characteristic features of MNCs such as large Stokes shift, 3 high photostability, 3 and low cytotoxicity 4 enable their versatile applicability in multidisciplinary areas such as optoelectronics, 5 sensing, 6 catalysis, 7 antibacterials, 8 drug delivery, 9 and bioimaging. 10,11 MNCs of coinage metals like Au and Ag have garnered significant attention and have been explored more compared to CuNCs owing to their higher reduction potential and increased stability after formation.…”
