OPTICAL FIBER TYPE SURFACE PLASMON ENHANCED FLUORESCENCE MEASUREMENT DEVICE AND PLASMON EXCITATION SENSOR USED IN THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical fiber type surface enhanced fluorescence measurement device which is capable of detecting a desired analyte with high precision by applying optical fiber technology to surely collect fluorescent light and is capable of easily detecting the desired analyte without controlling a resonance angle of excitation light, and to provide a plasmon excitation sensor used in the same.;SOLUTION: A plasmon excitation sensor used in an optical fiber type surface enhanced fluorescence measurement device has an optical fiber structure comprising at least a core part made of a columnar dielectric member having metal fine particles dispersed therein and a clad part provided on the outside of the core part in a concentric-circle state and having, on an inner surface, a reaction layer for capturing an analyte labeled by a fluorochrome and is configured so that an electric field of the metal fine particles is enhanced by irradiation of excitation light from a light source to one side end part of the core part to excite the fluorochrome in the reaction layer and thereby enhanced fluorescent light is detected by optical detection means.;COPYRIGHT: (C)2012,JPO&INPIT
