Title:
金属微細構造体および検出装置
Document Type and Number:
Japanese Patent JP7398639
Kind Code:
B2
Abstract:
One non-limiting and exemplary embodiment provides a metal microscopic structure capable of detecting a low-concentration analyte with high sensitivity. The metal microscopic structure includes a base member including multiple protrusions arrayed at predetermined intervals, and multiple projections made of a metal film covering the base member and configured to generate surface plasmons upon irradiation with light. A film thickness of the metal film positioned in a bottom portion of a gap between every adjacent two of the multiple projections is greater than a height of the multiple protrusions and is more than or equal to 90% and less than or equal to 100% of a film thickness of the metal film deposited on top portions of the multiple protrusions.
