FLUORESCENT SENSOR AND ANALYTE COMPONENT MEASUREMENT METHOD

Title:

FLUORESCENT SENSOR AND ANALYTE COMPONENT MEASUREMENT METHOD

Document Type and Number:

Japanese Patent JP2014224680

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a fluorescent sensor of which the lifetime can be extended.SOLUTION: The fluorescent sensor includes an indicator layer 5 containing a fluorescent substance which detects an analyte component of a living body and emits fluorescence according to the amount of the analyte component in response to irradiation with excitation light, a photo diode 3 receiving the fluorescence to output an electric signal according to the intensity of fluorescence, and a light source 6 for irradiating the indicator later 5 with the excitation light. The indicator layer 5 is disposed on the photo diode 3, and the light source 6 is configured so that the inside of the indicator layer 5 is irradiated with the excitation light emitted therefrom in a direction parallel with a light receiving surface of the photo diode 3.
