Self-assembly is a process where molecules or particles spontaneously organize themselves into structured patterns or shapes without external guidance. This phenomenon occurs in various natural and synthetic systems, such as in the formation of cell membranes or the arrangement of nanoparticles. In nature, self-assembly plays a crucial role in biological processes, like the way proteins fold into functional shapes. In technology, researchers are exploring self-assembly for applications in materials science, such as creating new materials or drug delivery systems, leveraging the inherent properties of nanoparticles and biomolecules.
