According to one embodiment, a measuring system using an optical waveguide is provided. The measuring system has an optical waveguide, magnetic fine particles, a magnetic field applying unit, a light source and a light receiving element. The optical waveguide has a sensing area to which first substances having a property of specifically bonding to subject substances to be measured are fixed. Second substances having a property of specifically bonding to the subject substances are fixed to the magnetic fine particle. The magnetic field applying unit generates a magnetic field for moving the magnetic fine particles. The light source inputs a light into the optical waveguide. The light receiving element receives the light output from the optical waveguide.

An optical waveguide type antibody chip includes a transparent substrate, an incident-side optical element and an emitting-side optical element placed at a distance from each other on a primary face of the substrate, a water repellent resin film formed on the primary face of the substrate including an optical waveguide layer formed between the optical elements, the water repellent resin film includes a reaction hole having exposed the optical waveguide layer on its bottom and a frame-shaped trench surrounding the reaction hole, a rectangular frame-shaped cell wall which is fixed in the trench of the water repellent resin film and which forms a cell capable of infusion and discharge of a specimen solution together with the reaction hole, and an antibody immobilization layer formed on the bottom of the reaction hole, the surface of the antibody immobilization layer being masked with at least a buffer agent and a salt.
摘要:
A microwave cooking apparatus having a frypan which may be used both for microwave cooking and cooking with fire so that a burned portion may be quickly obtained on the food while the inside of the food is also sufficiently heated. The frypan has a handle which does not become hot in the microwave apparatus. A rotating plate may be controlled to stop when the handle is in a desired position. Dish receiving shelves may be formed in the microwave apparatus which are spaced at a distance greater than the diameter of the frypan.
