“…[60] The as-prepared lysozyme-Cu NCs showed superior biocompatibility and were successfully applied to visualize various cancer cells (NIH3T3 cells, MCF7 cells, and MDA-MB-231 cells). Similarly, GSH [61] and L-methionine [62] were independently used as ligands for the synthesis of Au NCs for Co 2+ and Ag + ions sensing. The as-prepared GSH-and L-methionine Au NCs exhibited emission peaks at 500 and 536 nm, interestingly both exhibited different sensing mechanisms.…”

In the past 2 decades, multicolour light‐emissive nanomaterials have gained significant interest in chemical and biological sciences because of their unique optical properties. These materials have drawn much attention due to their unique characteristics towards various application fields. The development of novel nanomaterials has become the pinpoint for different application areas. In this review, the recent progress in the area of multicolour‐emissive nanomaterials is summarized. The different emissions (white, orange, green, red, blue, and multicolour) of nanostructure materials (metal nanoclusters, quantum dots, carbon dots, and rare earth‐based nanomaterials) are briefly discussed. The potential applications of different colour‐emissive nanomaterials in the development of fluorescent inks, light‐emitting diodes, cell imaging, and sensing devices are briefly summarized. Finally, the future perspectives of multicolour‐emissive nanomaterials are discussed.

“…In catalysis, AuNCs showed up to 100% conversion and selectivity in the semihydrogenation of terminal alkynes, hydrogenation of nitrobenzaldehyde derivatives in water, oxidation of styrene to benzaldehyde, and selective oxidation of sulfide to sulfoxide . Furthermore, AuNCs catalyze water splitting and oxygen reduction reactions, and due to their light-harvesting properties, AuNCs can be used as photosensitizers in photovoltaic and photocatalytic applications ,,− as well as in selective and sensitive detection of metal ions in water. − Because of their low immunogenicity, low clearance time, and high biocompatibility, glutathione (GSH)-stabilized AuNCs are promising candidates for medical applications such as tumor and bone imaging, , as photosensitizers in photodynamic therapy, and for targeted delivery and drug release in tumor treatment. , …”

The chromatographic separation of atomically precise glutathione-stabilized gold nanocluster (AuNC) mixtures is demonstrated for purely aqueous anion exchange chromatography (AEX) and compared to the results of hydrophilic interaction liquid chromatography (HILIC), which requires mixtures of water and acetonitrile. For isocratic HILIC separations, the influence of the mobile phase composition with respect to ionic strength and acetonitrile content is investigated. Individual AuNCs are identified by their optical properties directly from chromatograms and by comprehensive electrospray ionization differential mobility mass spectrometry. Separations by AEX are performed in aqueous mobile phases and are thus considered as a green and sustainable technique for the efficient fractionation of AuNCs. Henry coefficients are determined, which describe the retention behavior of single AuNCs and thus form the basis for modeling, optimization, and scale-up of the separation. The separation by AEX is optimized by linear salt gradient experiments. The scalability of the separation is demonstrated by increasing the AuNC feed concentration up to 64 g/L. Moreover, we quantify the amounts of individual AuNCs by inductively coupled plasma–optical emission spectroscopy after separation and close the mass balance demonstrating the reversible adsorption from the stationary phase. Our AEX approach is superior to HILIC since it offers a higher resolution, provides access to larger clusters, is readily scalable, and is purely water-based. AEX is considered as a sustainable, scalable, and widely applicable technique for the isolation of all types of water-soluble single cluster species. Therefore, we anticipate applications for instance for highly specialized nanocatalysts, sensors, or in medicine.
