Abstract:
A sample chip analyzing device comprising:a waveguide plate which entirely reflects and wave-guides incident light, and which includes a surface on which a number of sampling probes are fixed, the sampling probes being coupled to samples to be analyzed that are labeled with a fluorescent substance; a light source, provided in a light-shielding box having an opening into which an end portion of the waveguide plate is inserted in a light-shielded state, for introducing fluorescent excitation light into the waveguide plate through the end portion of the waveguide plate inserted into the light-shielding box; and a pickup member for picking up an image of substantially an entire surface of the waveguide plate, and outputting picked-up data of fluorescence; wherein the fluorescent substance labeled on the samples coupled to the probes is excited by an evanescent wave generated when the waveguide plate wave-guides the fluorescent excitation light from the light source into an interior of the waveguide plate, and entirely reflects the fluorescent excitation light; and wherein the samples are analyzed by detecting respective ones of the sampling probes that are coupled to the labeled samples, based on the picked-up data of fluorescence outputted by the pickup member.
