SAMPLE DETECTION APPARATUS AND DETECTION METHOD

摘要

According to one embodiment, a sample detection apparatus including an insulating partition to divide a first and a second region, a pore formed in the partition, a first electrode arranged in the first region, a second electrode arranged in the second region, a power source configured to apply electrical current between the first and second electrode in a state in which a reagent containing a capture substance to be bound to a target and a tag particle bound to the capture substance is introduced into the first region together with a sample, and an electrolyte solution is introduced into the second region, a measurement unit configured to observe a change in a conductive state, and a detection unit to detect presence/absence of the target in the sample based on an observation result.

1. A sample detection apparatus comprising:
an insulating partition configured to divide a first region and a second region; a pore formed in the partition and configured to make the first region and the second region communicate; a first electrode arranged in the first region; a second electrode arranged in the second region; a power source configured to apply electrical current between the first electrode and the second electrode through the pore in a state in which a reagent containing a capture substance to be specifically bound to a target and a tag particle bound to the capture substance is introduced into the first region together with a sample, and an electrolyte solution is introduced into the second region; a measurement unit configured to measure a change in a conductive state between the first electrode and the second electrode when the target and the tag particle to be detected in the first region passes through the pore; and a detection unit configured to detect presence/absence of the target to be detected in the sample based on a measured result of the measurement unit.
