Abstract: An optical detection type chemical sensor includes a light source, a detection element and a photodetector. The detection element is constituted of a laminate in which a multilayer film including a chemical detection layer, an optical interference layer, and a half mirror layer is formed on a transparent substrate. At least one of the layers includes a magnetic material. Light from the light source is applied to the detection element under the condition that the light enters inside of the detection element from the rear surface of the transparent substrate on which the laminate is not formed and multiple reflection occurring in the laminate intensifies the magneto-optical effect. A subject is detected by using the photodetector to detect a magneto-optical signal indicating a change in reflected light from the laminate resulting from a change in an optical property resulting from a reaction in the chemical detection layer.

Abstract: A fluorescent image analyzer stores a reference fluorescent-sample image and a subject fluorescent-sample image. The reference fluorescent-sample image is an image obtained by illuminating a reference fluorescent sample about which relation of in-plane fluorescence intensities is known with linearly polarized light and capturing a first specific polarization component of fluorescence from the reference fluorescent sample. The subject fluorescent-sample image is an image obtained by illuminating a subject fluorescent sample with linearly polarized light and capturing a second specific polarization component of fluorescence from the subject fluorescent sample. The fluorescent image analyzer is configured to determine correction coefficients to correct non-uniformity in measurement of light intensities among pixels of a captured image based on the reference fluorescent-sample image, and correct light intensities of the pixels of the subject fluorescent-sample image based on the correction coefficients.

Abstract: Provided is a support for fluorescence polarization immunoassay of which reaction parts are loaded with an antibody and a fluorescent labeling substance. The plurality of reaction parts may be loaded with different concentrations of an antibody and a fluorescent labeling substance. Further, antibodies having different binding affinities for a target substance may be loaded. With such a support, fluorescence polarizations can be measured simply by adding a sample solution containing a target substance to the reaction parts, and a wide measurement range of the concentration the target substance can be secured.
