Abstract:
1. A nucleic acid detection device used to a target nucleic acid detection utilizing an electrochemical response of a nucleic acid recognition body, comprising: a flow channel that allows a solution containing the nucleic acid recognition body to flow therethrough and includes a curved portion and a straight portion that is continued from and located downstream of the curved portion; probe electrodes having immobilized nucleic acid probes and arranged at intervals along the straight portion so as to avoid an upstream end of the straight portion that is located within a distance L from the curved portion, the distance L being given by: where ρ is a concentration of the solution, u is a flow velocity of the solution, μ is a viscosity of the solution, S is a sectional area of the flow channel, and Lp is a wall peripheral perimeter of the flow channel; and at least one counter electrode provided in the flow channel and used to measure the electrochemical response of the nucleic acid recognition body.
