An ionic polymer that binds to an ionic polymer such as DNA is identified. In order to identify an ionic polymer that is positively charged, for example, another, negatively charged, polymer is immobilized on a substrate or a bead. A positively charged ionic polymer is adsorbed on the substrate or bead. When the surrounding ionic environment is suddenly decreased, the adsorbed complex is stabilized, whereas the structure of the immobilized, non-adsorbed ionic polymer becomes unstable. By providing the immobilized ionic polymer with a marker for differentiating a stable structure from an unstable one, it can be determined on which immobilized ionic polymer the ionic polymer to be identified has been adsorbed.
