Abstract
Official abstract text for this publication.
Performing a measurement using an optical field enhancement device which includes a transparent substrate having a transparent fine uneven structure on a surface and a metal film formed on a surface of the fine uneven structure on the surface of the substrate, in which a subject is placed on the metal film of the optical field enhancement device, then excitation light is projected onto an area of the optical field enhancement device on which the subject is placed, and light generated by the projection of the excitation light is detected from a back surface side of the transparent substrate.
First claim
