MICROCHANNEL CHIP AND MICROARRAY CHIP

摘要

A microchannel chip is provided that is easily mountable irrespective of limitation of arrangement of devices therearound and relatively inexpensive in manufacturing cost. The microchannel chip includes: a substrate holder including a recess; a reaction substrate mounted in the recess of the substrate holder; a first sheet disposed so as to cover the substrate holder and the reaction substrate; and a second sheet disposed so as to cover the first sheet. The reaction substrate includes: a first surface exposed to the reaction chamber; and a second surface exposed to the outside through an observation window provided on the recess of the substrate holder. A reaction spot including a microstructure is formed on the first surface of the reaction substrate. The reaction spot is exposed to the reaction chamber.
