Abstract: A first frame having a first through-hole is arranged on a support so that one opening of the first through-hole is closed. A liquid containing a capturer for capturing a substance to be detected is fed into the first through-hole, and the capturer is immobilized on the support exposed in the first through-hole. After removing the liquid from the support, a second frame having the second through-hole is arranged on the support in the first through-hole so that one opening of the second through-hole is closed.

Abstract: Provided is a position detection method and a position detection device for detecting a position of a sensor chip and obtaining relative positional information between a well member and a prism as for a well chip type sensor chip in which the well member is provided on a prism. By applying measurement light to the sensor chip while changing a distance between the sensor chip and a measurement light irradiation unit and detecting reflected light traveling in a predetermined direction out of the reflected light generated when the measurement light is reflected by the sensor chip, at least any one of the position of the sensor chip and the relative position between a dielectric member and a sample solution holding member is detected on the basis of a change in intensity of the detected reflected light.

Abstract: The present invention pertains to a surface plasmon enhanced fluorescence analysis device and a surface plasmon enhanced fluorescence measurement method which use GC-SPFS and make it possible to detect a substance to be detected with high sensitivity. This surface plasmon enhanced fluorescence measurement device has: a light source for irradiating the diffraction grating of a chip with excited light; a polarizer for removing linearly polarized light from fluorescent light emitted from a fluorescent substance on the diffraction grating; and a photodetector for detecting the linearly polarized light removed by the polarizer.

Abstract: This detection device has a holder and a heating unit. The holder holds a detection chip that has the following: a prism that has an incidence surface and a film-formation surface; a metal film formed on said film-formation surface; trapping bodies laid out on the surface of said metal film; and a substrate that is laid out on the surface of the metal film, and together with the metal film, forms a liquid collection section in which a liquid is collected. The heating unit heats at least one of the substrate, the prism, and the metal film either while in contact therewith or without contacting same. Also, the heating unit is positioned so as to avoid the path that excitation light takes from an excitation-light emission unit to the abovementioned incidence surface.
