Title:
ANALYSIS METHOD AND ANALYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/031514
Kind Code:
A1
Abstract:
Laser light (50a) is irradiated on an analysis substrate (1), reflected light from a reaction region (10) is received, and a light reception level signal (JS) is generated. Furthermore, in the reaction region (10), a light reception level signal (JS) having a signal level higher than a prescribed signal level (Lth) is extracted as a particle detection signal (KS), and a substance to be detected (11) is detected on the basis of the extracted particle detection signal (KS). The analysis substrate (1) has: the reaction region (10) on which are captured first particles (20) provided with the substance to be detected (11) and antibodies (21) that recognize the substance to be detected (11), and second particles (30) provided with an antigen (31) that bonds with the antibodies (21), the second particles (30) being formed from a metal; and a non-reaction region (9) on which the reaction region (10) is not formed. The analysis substrate (1) is formed of a resin material.
