“…Proteins, such as BSA, HSA, pepsin, and Lys, are commonly used as biotemplates for metal NCs (Figure 3b). [47,[68][69][70][71] In particular, the sulfhydryl groups of protein molecules are key binding sites in the synthesis process. In other cases, proteins with histidine residues can coordinate with metal ions to form NCs.…”

Metal nanoclusters (NCs) are well‐recognized novel nano‐agents that hold great promise for applications in nanomedicine because of their ultrafine size, low toxicity, and high renal clearance. As foreign substances, however, an in‐depth understanding of the bioresponses to metal NCs is necessary but is still far from being realized. Herein, this review is deployed to summarize the biofates of metal NCs at various biological levels, emphasizing their multiscale bioresponses at the molecular, cellular, and organismal levels. In the parts‐to‐whole schema, the interactions between biomolecules and metal NCs are discussed, presenting typical protein‐dictated nano–bio interfaces, hierarchical structures, and in vivo trajectories. Then, the accumulation, internalization, and metabolic evolution of metal NCs in the cellular environment and as‐imparted theranostic functionalization are demonstrated. The organismal metabolism and transportation processes of the metal NCs are subsequently distilled. Finally, this review ends with the conclusions and perspectives on the outstanding issues of metal NC‐mediated bioresponses in the near future. This review is expected to provide inspiration for tailoring the customization of metal NC‐based nano‐agents to meet practical requirements in different sectors of nanomedicine.

“…Various ligands have different coordination kinetics and then change the HOMO and LUMO levels of NCs differently which can change both quantum yield and emission wavelength of NCs. Other methods include AIE, encapsulation in mesoporous materials and metal organic frameworks (MOFs), changing the size of NCs, doping with heteroatoms, etc. These aspects are discussed in Section .…”

Nanoclusters are nanostructures consisting of few to tens of atoms which have attracted great interest from the scientific community due to their applications in a myriad of fields, from catalysis to biomedical applications. Due to the discrete energy levels resulting from their ultrasmall size, nanoclusters exhibit distinctly different chemical, optical, and electrical properties compared with their larger nanoparticle counterparts. Unlike previously reported nanostructures with larger dimensions (1–10 nm), which typically have a single advantage (for example, high conductivity or optical properties), nanoclusters can be used as signaling and/or reaction-accelerating materials in almost all sensing assays with enhanced properties. Nanoclusters are among the most promising luminescent emitters (electrochemiluminescent, fluorescent, chemiluminescent, and colorimetry) with high quantum yield and better biocompatibility than conventional emitters. Considering their excelent biocompatibility, tailored modification, and desirable electrochemical and optical tunability, nanoclusters have opened new horizons in designing high-performance sensing and biosensing devices. In addition, they represent excellent electrochemical and photoelectrochemical behaviors with improved functionality and environmentally friendly properties compared to traditional compounds. This review discusses the recent advances in nanoclusters, their applications in sensing and biosensing, current limitations, and prospects to overcome these challenges. The present study gives a much brighter vision of nanoclusters that discusses one by one their particular advantages and role in developing sensing frameworks.

Bimetallic gold (Au) catalysts present an exceptional development trend toward enhancing the catalytic efficiency of the Au based catalysts. The aim of this review is to provide an insight into synergic effect of the bimetallic Au catalysts in enhancing the efficiency of various processes. The review covers some important aspects involving the effect of particle size, composition, metal-support interaction, morphology and the interaction between Au atom and the secondary metal on catalytic properties of the bimetallic Au catalysts. Particularly, the effect of the core–shell and faceted bimetallic Au catalysts morphologies are clearly articulated in the introduction. In the next section, various spectroscopic and microscopic characterization techniques, which often form a basis for the discussion of the synergic effect of the catalysts in enhancing the process efficiency are also discussed. Finally, we provide a summary on the progress made in catalytic exploration of bimetallic Au catalysts focusing in oxidation of hydrocarbons, fuel cell processes, oxidative transformation of the biomass derived products and photocatalysis.
