ABSTRACT:
A nucleic acid detection device includes a flow channel through which a solution containing a nucleic acid recognition body flows, probe electrodes having immobilized nucleic acid probes, and a counter electrode used to measure an electrochemical response of the nucleic acid recognition body. The flow channel includes a curved portion and a straight portion continued from and located downstream of the curved portion. The probe electrodes are arranged at intervals along the straight portion, avoiding an upstream end of the straight portion that is located within a distance L from the curved portion. The distance L is given by L=0.065×Re×D, Re=ρuD/μ, and D=4S/Lp where ρ, u, and μ are a concentration, a flow velocity, and a viscosity of the solution, and S and Lp are a sectional area and a wall peripheral perimeter of the flow channel, respectively.
