Abstract:
1. A hybridization detecting unit, comprising: a reaction region in which hybridization takes place, the reaction region having a top region and a bottom region, the reaction region being defined by a substrate in the bottom region, a defining layer on the substrate, and an upper layer in the top region on the defining layer, wherein the defining layer includes a well having a first side wall and a second side wall; sites including first electrodes in the top region or the bottom region, the sites being in the well and having detection nucleic acids affixed thereto; one or more second electrodes in the bottom region or the top region, the one or more second electrodes opposing the sites; an opposed electrode in the first side wall; and an opposed electrode in the second side wall, one of the opposed electrodes being smaller than the other of the opposed electrodes.
