Isäntävierasvuorovaikutus, often translated as host-guest interaction, refers to the binding between two different molecules. One molecule is termed the host, and the other is the guest. The host molecule possesses a cavity or pocket where the guest molecule can fit. This interaction is typically non-covalent, meaning it relies on weaker forces such as hydrogen bonds, van der Waals forces, electrostatic interactions, and hydrophobic effects, rather than the strong covalent bonds that form chemical compounds.

The specificity of host-guest interactions is a key feature. The size, shape, and chemical properties of both the host's cavity and the guest molecule determine the strength and selectivity of their binding. This allows for the design of host molecules that can selectively bind to specific guest molecules from a mixture. This principle is foundational in various fields, including supramolecular chemistry, molecular recognition, and drug delivery.

Applications of host-guest interactions are widespread. They are utilized in artificial receptors for sensing and detecting specific analytes, in catalysis to create microenvironments that facilitate reactions, and in separation technologies to isolate desired substances. In biology, such interactions are fundamental to processes like enzyme-substrate binding, antibody-antigen recognition, and DNA-protein interactions, where specific molecular recognition is crucial for biological function. The study of host-guest interactions aims to understand and mimic these natural recognition processes for technological advancements.
