摘要:
A testing chip that analyzes a specimen includes: a reagent storage section; a mixing and reaction flow channel to perform a series of operations to mix a specimen and aqueous reagent, make the specimen and reagent react with each other, and detect the reaction; and a liquid feed control section provided between an outlet flow channel of the reagent storage section and the inlet of the mixing and reaction flow channel. Herein, aqueous reagent, lipophilic liquid, and aqueous liquid having greater surface tension than that of the aqueous reagent are disposed in the reagent storage section in this order toward the outlet flow channel, the aqueous liquid being stored in contact with the liquid feed control section; and aqueous liquid passes the micro flow path of the liquid feed control section by applying a liquid feed pressure higher than or equal to a predetermined pressure to the reagent storage section.

A testing microchip includes a specimen storage section; a reagent storage section; a reaction section; a testing section for a test of a reaction product obtained from the reaction; a liquid feed control section; and a gas bubble trapping structure. The sections are connected continuously by a series of flow channels. The liquid feed control section stops passing of liquid until a liquid feeding pressure reaches a predetermined pressure, and passes the liquid when the liquid feeding pressure becomes higher than the predetermined pressure; and the gas bubble trapping structure traps a gas bubble in the liquid that flows in the flow channel so that the gas bubble does not flow to the downstream side and only the liquid passes to the downstream side. A testing apparatus that performs testing in the testing section of the testing microchip, wherein the testing microchip is attachably and detachably mounted to the apparatus.

摘要:
A microchip capable of sending liquid in a micro flow channel to a predetermined place irrespective of the pressure difference and sending a mixture of two or more liquid masses to a predetermined place even if the channel structure is simple. The microchip comprises an intermediate reservoir portion provided in a micro flow channel and adapted for temporarily holding liquid sent through the micro flow channel. The microchip is characterized in that the intermediate reservoir portion has a side channel, the volume of the intermediate reservoir portion is smaller than the total volume of the liquid sent into the intermediate reservoir portion, the side channel is provided for communication of a micro flow channel on the upstream side of the intermediate reservoir portion with a micro flow channel on the downstream side thereof, and the cross-section area of the side channel is smaller than that of the micro flow channel.
