Supramolecular assembly refers to the organization of molecules into larger, structured complexes through non-covalent interactions, such as hydrogen bonding, van der Waals forces, and electrostatic interactions. This process allows for the formation of intricate structures that can exhibit unique properties not found in individual molecules, making it a key area of study in fields like chemistry, materials science, and biotechnology. These assemblies can be found in nature, such as in DNA and protein structures, and can also be engineered for various applications, including drug delivery systems and nanotechnology. By manipulating the interactions between molecules, scientists can design materials with specific functions and behaviors, paving the way for innovative solutions in medicine and technology.
