A metal layer 13 made of Au or the like is formed on the upper surface of a transparent substrate 12. Dielectric layers 14a, 14b and 14c with different thicknesses are formed on the upper surface of the metal layer 13 (any one of the dielectric layers can have a thickness of 0) to form respective determination areas 15a, 15b and 15c. Further, different types of antibodies 22a, 22b and 22c are fixed on the upper surfaces of the respective dielectric layers 14a, 14b and 14c. Then, light is directed to the determination areas 15a, 15b and 15c, then signals of light reflected by the determination areas 15a, 15b and 15c are received, the light is dispersed, and analyses are performed on signals resulted from the light dispersion to detect the conditions of the surfaces of the respective determination areas, at the same time.

In a surface plasmon resonance sensor including a chip with a substrate 102 and a metal layer 103, a prism 104, an optical system 105 serving as a light source, and a light detector 106, the metal layer 103 is configured by a flat part 109 formed into a thin film, and convex parts formed from metal particles 110 and the like arranged spaced apart from each other. When light enters the metal layer 103 of such configuration, resonance angle arising from the flat part 109 and the convex parts are respectively obtained. The change in index of refraction of a medium contacted by the metal layer is detected from such resonance angle.

A substrate for immobilizing biomolecules comprises a chip substrate, a hydrophilic monolayer, and a lipid bilayer, and a biochip comprising the substrate for immobilizing biomolecules on which biomolecules are immobilized. The substrate for immobilizing biomolecules includes a transparent chip substrate, a metal layer provided on the chip substrate, a monolayer provided on the metal layer, and a lipid bilayer provided on the monolayer. The metal layer is composed of fine particles of Au, the monolayer is composed of self-assembled molecules represented by X—(CH2)n—OH (where X is a thiol group), and the lipid bilayer is composed of self-assembled phospholipids. The monolayer and the lipid bilayer are relatively flexibly bound together via hydrogen bonds. In the biochip, a receptor is immobilized on the lipid bilayer via a biorecognition molecule.

摘要:
A sensor chip has a metal layer formed on a surface of a substrate, where a plurality of microscopic concave part is formed in a measurement region of the surface of the metal layer. When light of linear polarization is irradiated onto the measurement region, local resonance electric field generates at opposing metal layer surfaces in the concave part. The reflected light thereof is received to measure reflectance. The light of linear polarization is irradiated so that the polarizing surface becomes orthogonal to the longitudinal direction of the concave part.

At both ends of a waveguide 43 having a plurality of cores 51, light emitting elements 47 and light receiving elements 49 are disposed so as to face end faces of the cores 51. A switch 44 is overlapped over the waveguide 43. In the switch 44, switching windows 52 each can be switched between a state where light propagating through the core 51 is passed and a state where the light is reflected are arranged in the vertical and horizontal directions, and the switching windows 52 are arranged along the top faces of the cores 51. A test board 45 having a plurality of channels 60 in each of which a metallic thin film 61 is formed is disposed over the switch 44, and receptors 62 are fixed on the metallic thin film 61 in the channels 60. A specimen containing a specific ligand is passed in each of the channels 60.

A biochip includes a liquid crystal panel having liquid crystal cells each corresponding to each sample on a substrate. The liquid crystal panel includes an upper polarization filter, an upper transparent electrode, an upper orientation film, a liquid crystal, a lower orientation film, a lower transparent electrode and a lower polarization filter in this order. By application of voltage to a desired liquid crystal cell, external light is selectively radiated onto the sample. Thus, it is possible to achieve downsizing, cost reduction and high-speed operation of a biochip reader.
