DETECTOR AND DETECTION METHOD

摘要

There are provided a detector and a detection method capable of detecting a biological sample with high sensitivity. A detector (50) is provided with a microchamber array (4) including a plurality of storage sections (8) to be filled with a hydrophilic solvent containing a biological sample; and an image sensor (2) in which picture elements 5 are disposed corresponding to the storage sections (8), wherein the microchamber array (4) includes a flow channel (54) in communication with openings (10) of the storage sections (8); a hydrophobic solvent supply unit (56) arranged in continuity with the flow channel (54); and a through-hole (58) which allows the hydrophilic solvent (42) to enter and exit the flow channel (54), and the hydrophobic solvent supply unit (56) flows a hydrophobic solvent (44) into the flow channel (54) by an externally-applied force.
