ABSTRACT:
A device is provided for a chemical reaction between molecules immobilized on a solid phase and molecules in a solution. A chemical analysis device is also provided to capture molecules in the solution and subsequently measure the captured molecules. Reaction efficiency and sample throughput are thereby improved. The chemical reaction and chemical analysis devices use a microfluidic device channel as a reaction vessel. The channel is provided with a particular molecule immobilized on an interior surface of the channel with an obstacle positioned against the flow. In a typical reaction vessel having an enzyme immobilized in the capillary's interior surface and glass beads as obstacles, a reaction solution can move either in one direction or back and forth to react with the immobilized enzyme. The flow of the reaction solution is not laminar such that a reaction between the particular molecule and the reaction solution proceeds at high efficiency.
