<p>A bioassay method in which the efficiency of an interaction between substances such as hybridization is enhanced by controlling the production of an electric field in a reaction region where the interaction occurs, and a bioassay device for preferably implementing the method are disclosed. The method is conducted to detect an interaction between substances by using a detector (1(10)) at least having a detection surface (S(S’)) subjected to a surface treatment for fixing a substance D for detection, a reaction region (R(R’)) for providing a field where an interaction between the detection substance D fixed to the detection surface (S(S’)) and an added target substance T occurs, and electric field producing means (E) for producing an electric field in the reaction region (R(R’)) by causing a potential difference in the reaction region (R(R’)). The method comprises a procedure of turning on/off the electric field producing means (E) at a predetermined timing so as to produce/extinguish an electric field.</p> |
