METHOD FOR MANUFACTURING MICROCHIP FOR LIQUID SAMPLE ANALYSIS

Document Type and Number:

WIPO Patent Application WO/2022/045355

Kind Code:

A1

Abstract:

A method for manufacturing a microchip for analyzing a component in a liquid sample by passing the sample through a flow path provided therein and causing reaction at a reaction part provided to a part of the flow path, the method comprising: a step (A) for preparing a substrate (1) having, on the surface thereof, a groove (11) which serves as the flow path and the reaction part (14) provided at a part between the two ends of the groove; a step (B) for applying a tackifier or an adhesive on a region other than where the groove is provided on the surface of the substrate; a step (C) for preparing a film (2) having a partial region (21) on which a reactive substance is applied; and a step (D) for adhering the film onto the substrate such that the groove on the substrate is covered with the film to form the flow path and such that the reaction part on the surface of the substrate having the tackifier or the adhesive applied thereon overlaps the region of the film on which the reactive substance is applied.
