    摘要： 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=4 S/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.

    摘要： A nucleic acid detection device is provided with a closed channel formed of a first channel portion, through which a washing reagent storage section for storing a washing reagent for washing a detection section for nucleic acid detection communicates with the detection section, and a second channel portion through which a pretreatment section for nucleic acid treatment communicates with the detection section. The closed channel is connected with a gas inlet/outlet path for communication with the outside. The gas inlet/outlet path is blocked by a sealing mechanism before nucleic acid detection. In storing a pretreatment reagent and the washing reagent frozen, the gas inlet/outlet path is kept open and connected to the channel. Thus, there is provided a nucleic acid detection device having a structure for preventing leakage of nucleic acid samples to the outside and which can be stored for a long period of time with the reagents therein.

    摘要： A device includes a flow channel through which a solution containing at least one of a target nucleic acid and a nucleic acid recognition body flows. The flow channel includes a flat bottom surface parallel to the flowing direction of the solution and an inclined surface gradually projecting from the bottom surface in the flowing direction. The device also includes a probe electrode provided on the inclined surface. The probe electrode is formed of an exposed portion of a metal film through an opening of a passivation film stacked on the metal film. An angle θ that the probe electrode forms with respect to the bottom surface, a maximal width R of the opening in the flowing direction, and a thickness d of the passivation film satisfy tan θ>d/R.
