Molecular recognition

Definition

Molecular recognition refers to the specific interaction between molecules, often mediated by non-covalent forces such as hydrogen bonding, electrostatic interactions, and van der Waals forces. This process is crucial in many biological and chemical systems as it enables the selective binding of molecules, which is essential for various functions like enzyme-substrate interactions, receptor-ligand binding, and self-assembly processes in nanoelectronics.
