BIOGENIC SUBSTANCE DETECTOR AND BIOGENIC SUBSTANCE DETECTION METHOD
First Claim
1. A biogenic substance detector comprising:
- a plurality of chambers, each of which has an area for fixing a probe for detecting a specific biogenic substance contained in a sample solution and is used to have the biogenic substance and the probe react with each other;
a passage provided between the chambers; and
a pump for allowing the sample solution to move back and forth within the chambers and the passage along a chamber-passage alignment direction;
wherein the passage having a cross-sectional area taken perpendicularly to the chamber-passage alignment direction is smaller than a cross-sectional area of each chamber taken perpendicularly to the chamber-passage alignment direction.

Abstract
A biogenic substance detector with high reaction efficiency and detection sensitivity is obtained.
The biogenic substance detector includes: a plurality of chambers 1011 for hybridizing a target and a probe; and a passage 1012 provided between the chambers 1011. The cross-sectional area of the passage 1012 taken perpendicularly to the chamber-passage alignment direction is smaller than the cross-sectional area of each chamber 1011 taken perpendicularly to the chamber-passage alignment direction, and a probe-fixing area 1013 is provided over the entire inside wall of each chamber 1011. One kind of probe is fixed in one chamber 1011. In the hybridization step, the sample solution is made to move back and forth within the chambers 1011 and the passage 1012 using a pump 102.

5. 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 a specific biogenic substance contained in the sample solution react with a probe fixed in the chambers to detect the biogenic substance; and a detection step of detecting the biogenic substance that has reacted with the probe; wherein in the reaction step, the sample solution is made to move back and forth within the chambers and the passage along a chamber-passage alignment direction, and the passage having a cross-sectional area taken perpendicularly to the chamber-passage alignment direction is smaller than a cross-sectional area of each chamber taken perpendicularly to the chamber-passage alignment direction. - View Dependent Claims (6, 7, 8, 9)
