Self-assembly

Definition

Self-assembly is a process where molecules automatically organize themselves into structured arrangements without external guidance. This phenomenon is driven by the inherent properties of the molecules involved, allowing them to spontaneously form patterns or structures, which is vital in various fields, including nanotechnology and materials science. It plays a crucial role in the bottom-up synthesis of nanomaterials and is also essential for enhancing the functionality of devices like displays through quantum dot color converters.
