|1. (WO2018100724) SPOT ARRAY SUBSTRATE, NUCLEIC ACID ANALYSIS METHOD, AND NUCLEIC ACID ANALYSIS DEVICE|
|Applicants:||HITACHI HIGH-TECHNOLOGIES CORPORATION
|Title:||SPOT ARRAY SUBSTRATE, NUCLEIC ACID ANALYSIS METHOD, AND NUCLEIC ACID ANALYSIS DEVICE|
The present invention improves throughput of nucleic acid analysis by preventing a reduction in S/B associated with increasingly higher integration of a spot array substrate. The present invention proposes a spot array substrate for nucleic acid analysis, in which spots are disposed in an array arrangement on the surface of a first material, while a region other than where the spots exist is covered with a second material, wherein a surface area increasing structure in which the height varies in a direction perpendicular to the substrate is formed at the portion where the spots exist so that the actual surface area becomes greater than the area defined by the outlines of the spots as viewed from above the substrate.
