BASE SEQUENCING ELECTRODE, BASE SEQUENCING DEVICE, AND BASE SEQUENCING METHOD

摘要

A base sequencing device comprising a conductive sensing electrode (2), blocking molecules (21) which are formed to cover the surface of the sensing electrode (2) to reduce adsorption of an inserting agent by the surface of the sensing electrode (2), a target complementary nucleic acid probe (23) which is immobilized on the sensing electrode (2) via a spacer member (22) formed of normal chain organic molecules and has a basic sequence complementary to a target basic sequence to be determined, a conductive reference electrode (3), and blocking molecules (31) which are formed to cover the surface of the reference electrode (3) to reduce adsorption of the inserting agent by the surface of the reference electrode (3).
