An aggregate of molecules, consisting of two to several hundreds of molecules.

Molecules are usually forms into aggregates called clusters by the intermolecular force, and their physicochemical behavior is sometimes different from that of bulks. Clusters are classified into the Van der Waals cluster, covalent cluster, hydrogen bond cluster, metal cluster, ionic bond cluster, and so on. These types of cluster are expected to be applied to surface modification and so on.
