MICRO ANALYSIS CHIP AND FABRICATION METHOD THEREOF

摘要

The present invention provides a novel micro analysis chip and a fabrication method thereof. The micro analysis chip comprises an inlet and a fluid flow path which communicates thereto. The fluid flow path comprises a first flow path, a second flow path, and a third flow path which are arranged continuously along a longitudinal direction of the fluid flow path. An antibody is bound on at least one peripheral surface selected from the group consisting of a peripheral surface of the second flow path and a peripheral surface of the third flow path. A cross-sectional area of the third flow path is constant or increased monotonically along a direction X from the second flow path toward the third flow path. A cross-sectional area of the second flow path is increased monotonically along the direction X from the one end to the other end of the second flow path. A cross-sectional area of the first flow path is larger than a cross-sectional area at the one end of the second flow path.
