Supramolecular systems are reversible and their dynamics is an inherent and essential property. The conceptual framework for kinetic studies of these systems is presented with a focus on the considerations required for experimental design. Selected examples for guest binding to cyclodextrins, cucurbit[n]urils, DNA, serum albumins and bile salt aggregates are presented that describe the type of information obtained from dynamic studies that are not available from thermodynamic investigations.
