nanoclustersand

Nanoclusters are aggregates of a small number of atoms or molecules, typically ranging from 2 to a few hundred constituents. Their properties are highly dependent on the specific number of atoms, their arrangement, and the type of element or molecule involved. Unlike bulk materials, nanoclusters exhibit unique electronic, optical, and chemical characteristics that often change dramatically with even slight variations in size. For example, a gold nanocluster might display distinct catalytic activity compared to a slightly larger or smaller gold nanocluster. This size-dependent behavior is a hallmark of nanoclusters and arises from quantum confinement effects and a high surface-area-to-volume ratio.

The study of nanoclusters is a significant area within nanoscience and nanotechnology. Researchers are exploring their potential applications in diverse fields such as catalysis, medicine (drug delivery and imaging), and materials science. Their precise control over composition and structure allows for the design of materials with tailored functionalities. Synthesizing nanoclusters often involves techniques like gas-phase condensation, solution-phase precipitation, and laser ablation. The stability of nanoclusters can be a challenge, as they are often prone to aggregation. Surface passivation or encapsulation with ligands is frequently employed to stabilize them. The term "nanoclustersand" does not refer to a recognized scientific term or material. It is likely a portmanteau or a misspelling. Therefore, this article focuses on the general concept of nanoclusters.
