    Abstract: The present invention provides a reciprocal-flow-type nucleic acid amplification device comprising:heaters capable of forming a denaturation temperature zone and an extension/annealing temperature zone; a fluorescence detector capable of detecting movement of a sample solution between the two temperature zones; a pair of liquid delivery mechanisms that allow the sample solution to move between the two temperature zones and that are configured to be open to atmospheric pressure when liquid delivery stops; a substrate on which the chip for nucleic acid amplification according to claim 2 can be placed; and a control mechanism that controls driving of each liquid delivery mechanism by receiving an electrical signal from the fluorescence detector relating to movement of the sample solution from the control mechanism; the device being capable of performing real-time PCR by measuring fluorescence intensity for each thermal cycle.

    Abstract: The invention provides a reciprocal-flow-type nucleic acid amplification method performing thermal cycling by reciprocating a sample liquid between a denaturation temperature zone and an elongation-annealing temperature zone with a connected microchannel including at least a curved channel corresponding to the denaturation temperature zone, a curved channel corresponding to the elongation-annealing temperature zone, a linear or curved intermediate channel that connects the aforementioned curved channels, and a connector to connect to a liquid delivery mechanism for enabling movement of the sample liquid. The method includes moving the sample liquid in the channel by the liquid delivery mechanism that is open to atmospheric pressure when liquid delivery is stopped, and measuring a fluorescence intensity for each thermal cycle at a predetermined point on the channel corresponding to the denaturation temperature zone and at a predetermined point on the channel corresponding to the elongation-annealing temperature zone to perform real-time PCR.

    Abstract: [Problem] To provide a target substance detection chip, a target substance detection device, and a target substance detection method, that can be manufactured easily in a small size at low costs with reduction of the number of parts involved in the detection chip constituted by an optical prism and a detection plate used for a SPR sensor and an optical waveguide mode sensor, that can detect a target substance quickly with high sensitivity, and in which an analyte liquid is easily delivered.[Solution] A target substance detection chip of the present invention includes: a plate-like transparent base portion which allows light to pass therethrough; and a flow path which is formed in one surface of the transparent base portion as a groove and through which an analyte liquid verifying a presence of a target substance is delivered in a length direction of the groove, wherein the flow path is formed such that at least an electric field enhancement layer is disposed on an inner surface of a groove portion formed to at least partly have inclined surfaces appearing in cross section to be inclined at a gradient to the surface of the transparent base portion, and wherein a part or entirety of an uppermost surface of the groove which contacts the analyte liquid serves as a detection surface for the target substance.
