Nanoclusters are small aggregates of atoms or molecules typically ranging from 1 to 100 nanometers in size. They possess unique physical and chemical properties due to their high surface-to-volume ratio and quantum effects. Applications of nanoclusters span various fields, including catalysis, where they enhance reaction rates; drug delivery, for targeted therapies; and sensors, providing increased sensitivity and selectivity. In electronics, nanoclusters are used in the development of nanocomposites and as components in nanoscale devices. Their tunable properties make them valuable in renewable energy technologies, such as photovoltaics and battery systems, enhancing efficiency and performance.
