ANALYSIS CHIP, ANALYSIS SYSTEM AND ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide an analysis chip by which a quantitative analysis by a competitive reaction can be performed.

SOLUTION: An analysis chip for analyzing a measuring object in a liquid sample includes a substrate; a development layer disposed on the substrate and capable of developing the liquid sample from one end side of the development layer to the other end side thereof; and an absorption layer disposed so as to be in contact with the other end side of the development layer. The development layer has a competitive reaction region that is at least a part of a region located between the one end side and the other end side and that has a competitive substance of the measuring object immobilized therein. The analysis chip further includes an electrode portion for detecting an electrochemical change in the competitive reaction region, the electrode portion being located on the competitive reaction region or on the surface between the competitive reaction region and the other end side of the development layer.
