In chemistry, polyvalency (or polyvalence, multivalency) is the property of molecules and larger species, such as antibodies, medical drugs, and even nanoparticles surface-functionalized with ligands, like spherical nucleic acids, that exhibit more than one supramolecular interaction.
Polyvalence or polyvalent may refer to: Polyvalency (chemistry), chemical species, generally atoms or molecules, which exhibit more than one chemical valence; Polyvalence (music), the musical use of more than one harmonic function of a tonality simultaneously; Polyvalent antibody, a group of antibodies that have affinity for various antigens
Polyvalence or multivalence refers to species that are not restricted to a specific number of valence bonds. Species with a single charge are univalent (monovalent). For example, the Cs + cation is a univalent or monovalent cation, whereas the Ca 2+ cation is a divalent cation, and the Fe 3+ cation is a trivalent cation.

Valence (chemistry), a measure of an element's combining power with other atoms; Valence electron, electrons in the outer shell of an atom's energy levels; Valence quarks, those quarks within a hadron that determine the hadron's quantum numbers; Degree (graph theory), also called the valency of a vertex in graph theory
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Due to cooperative effects stemming from polyvalency (chemistry), a polyvalent SNA-nanoparticle conjugate binds tighter to a complementary free linear strand than does the same sequence of DNA free in solution. [9] This finding has paved the way to the development of various detection methodologies based on this class of nanoparticles. [10] [11]
In chemistry, bifunctionality or difunctionality is the presence of two functional groups in a molecule.A bifunctional species has the properties of each of the two types of functional groups, such as an alcohol (−OH), amide (−CONH 2), aldehyde (−CHO), nitrile (−CN) or carboxylic acid (−COOH).
