Document Type and Number:
WIPO Patent Application WO/2010/134592
Kind Code:
A1
Abstract:
Provided is a high-sensitivity high-precision plasmon excitation sensor with which fluorescent signals generated in SPFS can be improved, an assay method using the sensor, an analyzer for SPFS, and a kit for the assay.
The plasmon excitation sensor is characterized by comprising a transparent planar substrate, a thin metallic film formed on one surface of the substrate, a layer constituted of a polymer affixed to the surface of the thin metallic film which is not in contact with the substrate and including a colloidal metal as base points, and a ligand affixed to the polymer, and by being subjected to a novel assay method based on an SPFS-LPFS system.
