    摘要: A nucleic acid cassette includes a main body in which first and second channels are formed. A sample containing a target nucleic acid is input in a sample chamber of the second channel via an injection port. In the cassette, a detecting part includes a detection chamber communicated to the first and second channels and a nucleic detection unit. The first channel has a first reagent reservoir storing a first reagent and a second reagent reservoir storing a second reagent. The first and second reagents reservoirs are separated by a gaseous body in the channel. The sample and the first and second reagents are supplied to the detecting part due to an action of a pump part communicated to the first and second channels.

    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.

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.
