Abstract:
1. A biogenic substance detection method comprising: a reaction step of supplying a sample solution to a plurality of chambers connected via a passage and having one of a plurality of biogenic substances contained in the sample solution react with one of a plurality of probes fixed in the chambers to detect the biogenic substance, a different probe being fixed in each of the chambers; and a detection step of detecting the biogenic substance that has reacted with the one probe; in the reaction step, the sample solution being made to move back and forth within the chambers and the passage along a chamber-passage alignment direction, the detection step comprising the steps of: the passage having a first cross-sectional area taken perpendicularly to the chamber-passage alignment direction that is smaller than a second cross-sectional area of each chamber taken perpendicularly to the chamber-passage alignment direction.
