Statement of Significance
Multivalency refers to the possibility of both synthetic and natural constructs, e.g., nanoparticles or viruses, to bind their target via multiple ligand-receptor bonds. Super-selectivity is a peculiar property of multivalent binding, first rationalised by Martinez-Veracoechea and Frenkel, and refers to the almost step-like response of the binding probability with respect to the number of receptors on the target. This commentary discusses the physical origins of this phenomenon, and how (combinatorial) entropy provides a fruitful point of view to understand ultra-sensitive responses involving multivalent agents.
