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.

摘要： 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.

摘要： The metal fine particles 33 are sparsely fixed on the surface of the transparent substrate 32, and the acceptor 35 for attaching the specific ligand is immobilized on the transparent substrate 32 or the metal fine particles 33. The prism 36 is closely attached to the lower surface of the transparent substrate 32, and the excitation light enters the transparent substrate 32 through the prism 36. The incident light is totally reflected at the surface of the transparent substrate 32, and the evanescent light generated at the surface and the metal fine particles 33 locally plasmon resonate. As the evanescent light and the metal fine particles locally plasmon resonate, a strong electric field is enclosed in the vicinity of the metal fine particles. When the surface arranged with the metal fine particles 33 and the acceptor 35 is contacted to the analysis sample solution containing ligand modified with light emitting molecules, only the light emitting molecule modifying a specific ligand attached to the acceptor emits light.

摘要： A method of mass-producing minute structures such as biochips, protein chips, quantum dots, and quantum chips involves arranging an antigen two-dimensionally on a board and arranging probes two-dimensionally facing the same direction so that the binding sites of the probes may bind to the antigen. An inorganic substance such as Ni is deposited on the board from the upper side of the probes by sputtering or evaporation to form a thin film layer and on the top surface of the flatly formed thin film layer, a supporting layer is formed by separating out the same inorganic substance using electrotyping. Then, by peeling the thin film layer and the supporting layer off of the board together, the mother stamper having cavities for the patterns of biomolecules is obtained.
