Gold nanocluster composites: preparation strategies, optical and catalytic properties, and applications

Abstract

Ultrasmall gold nanoclusters are widely investigated owing to their unique physical and chemical properties, while the poor fluorescence intensity and other weakness limit their application. To improve these properties and...

Synthesis and characterization of fluorescent gold clusters encapsulated in PNIPAM and PAAM hydrogels for selective detection of mercury in water

“…Also, the results demonstrate that the AuNCs are formed by photoreduction of the Au 3+ cations loaded inside of the hydrogel upon UV light irradiation, as it has been previously shown for similar systems. 54,55…”

“…Also, the results demonstrate that the AuNCs are formed by photoreduction of the Au 3+ cations loaded inside of the hydrogel upon UV light irradiation, as it has been previously shown for similar systems. 54,55 In order to study deeply the spectroscopic properties of the new materials, the excitation-emission matrix (EEM) of both, Au-PNIPAM NCs and Au-PAAM NCs, were determined and are shown in Fig. 9.…”

Fluorescent metal nanoclusters: prospects for photoinduced electron transfer and energy harvesting

“…[36][37][38][39] The high photostability of the MNCs is advantageous over the conventional organic fluorophores that are frequently used as biomarkers. 14,40,41 MNCs are thus widely used in sensing, bio-imaging, photodynamic therapy, electrochemiluminescence, biological tracking, and photovoltaic applications. [42][43][44] Recent progress in synthetic procedures, structures, and optical properties along with numerous applications of Au, Ag, and Cu NCs is well documented in numerous review articles.…”

Biomolecule-protected gold nanoclusters: synthesis and biomedical applications

“…A versatile hybrid platform is provided for bioimaging, 23 disease therapy, 24,25 and targeted drug delivery 26 applications (Scheme 1).Although several review articles have been devoted to AuNCs, these contributions have mainly focused on the diagnostic, sensing, and catalytic applications of AuNCs. [27][28][29] As an innovative nanomedical material, AuNCs have made tremendous advances in disease treatment and drug delivery, and therefore a recap review of their medical applications is urgently needed. In this review, the synthesis of AuNCs using biomolecules (proteins, peptides, DNA and polysaccharides) as templates is first described.…”
