SENSOR FOR DETECTING NUCLEIC ACID

摘要

PROBLEM TO BE SOLVED: To provide a sensor capable of detecting various kinds of nucleic acids at a high speed as well as with high accuracy. SOLUTION: This sensor for detecting various kinds of nucleic acids is characterized by the possession of both plural nucleic acid chain-immobilized electrodes (1402) each having a flat surface wherein probe nucleic acid chains are immobilized and the counter-electrodes (1405) each having a flat surface parallel to that of the mating electrode, then being disposed to form a flow path allowing a test liquid (1406) through between each of respective flat surfaces of the two electrodes and also playing a role in letting the current through between the two electrodes.
