Molecular aggregation is the process through which molecules come together and form larger structures, such as micelles, aggregates, or complexes, through non-covalent interactions such as van der Waals forces, hydrogen bonding, or hydrophobic interactions. This phenomenon is essential in various biological processes, such as protein folding and assembly, as well as in industrial applications like drug delivery systems or the formation of colloidal particles. Understanding molecular aggregation can provide insights into the behavior and properties of materials at a molecular level and can help in the design of new functional materials with specific properties.
