2021年12月12日 · For the past two decades, atomic gold nanoclusters (AuNCs, ultrasmall clusters of several to 100 gold atoms, having a total diameter of <2 nm) have emerged as promising agents in the diagnosis and treatment of cancer.

2023年4月26日 · Here, the authors report an alternative type of gold nanoclusters whose intrinsic chirality arises solely from the arrangement of the organic components on their surface.

2017年6月8日 · In this study, we found that it is possible to confer antimicrobial activity to Au NPs through precise control of their size down to NC dimension (typically less than 2 nm). Au NCs could kill both Gram-positive and Gram-negative bacteria.

2023年2月20日 · In this Review, we discuss the unique features of MPCs that make them ideal nanomaterials for applications in different fields, including catalysis and biological applications such as bioimaging,...

The centered icosahedral cluster Au 13 is the basis of constructing large gold nanoclusters. Au 13 is the endpoint of atom-by-atom growth. In other words, starting with one gold atom up to Au 12, each successful cluster is created by adding one additional atom.

2020年9月17日 · Our results demonstrate that single-atom substitution can substantially improve the CO 2 reduction selectivity of gold nanoclusters at large potentials. The dopant-induced ligand stability may serve as a design strategy to modify the …

For the past two decades, atomic gold nanoclusters (AuNCs, ultrasmall clusters of several to 100 gold atoms, having a total diameter of <2 nm) have emerged as promising agents in the diagnosis and treatment of cancer.

2023年7月21日 · Here, we identify the majority component in the seed solution as an atomically precise gold nanocluster, consisting of a 32-atom Au core with 8 halide ligands and 12 neutral ligands...

Gold nanoclusters are defined as clusters of gold formed by combining with one or more metallic elements. They exhibit unique properties such as enhanced electrical, optical, catalytic, and magnetic characteristics compared to individual metal nanoparticles.

Atomically precise gold nanoclusters are ideal model catalysts with well-defined compositions and tunable structures. Determination of the ligand effect on catalysis requires the use of gold nanoclusters with protecting ligands as the only variable.
