<P>PROBLEM TO BE SOLVED: To provide a surface plasmon excitation enhanced fluorescence measuring device capable of surely preventing adsorption of analyte to an area excluding a ligand fixing area and capable of highly accurately detecting fluorescence, and to provide a sensor structure to be used for the surface plasmon excitation enhanced fluorescence measuring device. <P>SOLUTION: The sensor structure to be used for the surface plasmon excitation enhanced fluorescence measuring device includes: at least, a dielectric member; a sensor member including a metallic thin film formed on the dielectric member, a ligand fixing area formed on the metallic thin film and a nonspecific adsorption prevention layer formed in an area on the dielectric member excluding the ligand fixing area; and a channel constitution member fixed on the sensor member and configured so that a sample solution can be circulated on the ligand fixing area and the nonspecific adsorption prevention layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
