A sensor chip includes: a transparent support; a metal thin film formed on one surface of the transparent support; and a reaction section in which a ligand is immobilized on an other surface of the metal thin film that is not in contact with the transparent support, wherein the sensor chip also includes a closed space-forming member which forms a closed space such that at least the reaction section is housed in the closed space, and water content in the closed space is adjusted to satisfy: X/Y&#x3c;10 (&#x3bc;g/mm) (wherein, X represents the water content in the closed space; and Y represents the surface area of the metal thin film in the closed space).

Sensor chip and method for storing sensor chip

A liquid feeding system for a microchip performs: a first liquid feeding step in which a sample liquid in a sample liquid containing section is fed in the direction to a primary containing section via a reaction field; a second liquid feeding step in which, after the first liquid feeding step, the sample liquid is fed from the primary containing section in the direction to the reaction field; and a third liquid feeding step in which, after the second liquid feeding step, the feedings of the sample liquid from and to the reaction field and the primary containing section a rear side gas-liquid boundary face of the sample liquid in the first liquid feeding step and the front side and rear side gas-liquid boundary faces of the sample liquid in the second and third liquid feeding steps do not pass through the reaction field.

Provided is an apparatus having a beam geometry changing device that changes the beam geometry of excitation light, and a control device that controls the beam geometry changing device, with favorable precision, which the apparatus performs a resonance angle scan and to detect a target material.

Surface plasmon-enhanced fluorescence measuring apparatus

To provide a surface plasmon-field enhanced fluorescence spectroscopic measurement method and a surface plasmon-field enhanced fluorescence spectroscopic measurement device which are capable of accurately measuring a fluorescent signal regardless of the type of a light detection means even when the concentration of an analyte is high by adjusting the dynamic range of the SPFS device. A surface plasmon-field enhanced fluorescence stereoscopic measurement method wherein an analyte labeled with a fluorescent substance is excited by surface plasmon light generated by applying excitation light to a metallic thin film, and generated fluorescence is received by a light detection means to thereby detect the analyte. The dynamic range is expanded by adjusting the amount of the fluorescence received by the light detection means.
