Abstract: A micro flow channel chip of the present invention has multiple grooves formed on a substrate to be connected with each other in parallel or in series and capillaries, chemically-modified in a manner different from each other, laid in the multiple grooves, wherein detected data can be obtained by supplying a fluid to the capillaries laid in the multiple grooves. The micro flow channel chip enables multiple items of chemical and biochemical functions to be measured simultaneously. The micro flow channel chip enables multiple items of chemical and biochemical functions to be measured simultaneously using micro flow channels formed on the substrate.

Abstract: A microchip pileup type chemical reaction system characterized in that a specified number of microchips, each having a reaction material liquid introducing section, a reaction product liquid discharge section and a reaction region, i.e. microchannels, interconnected therewith, are laid integrally in layers, the same kind of reaction material is introduced from the reaction material liquid introducing section into each microchip and the same kind of reaction product is collected from the reaction product liquid discharge section. The novel system for high efficiency chemical reaction makes the most use of the feature of microspace where general organic synthesis reaction is performed in the microchips while enabling mass synthesis.
