Visualization of odor quality and odor space information was examined using nano-reporter particle, which can respond to odor molecular information and sensor array. Selective odor sensing films were realized using molecular imprinted polymer and selectivity was analyzed with SPME-GC/MS method. The selectivity of the film could be reconfigured by a certain treatment, and then the film was suitable for the sensor array for the odor space measurement. Surface Plasmon-field enhanced Fluorescence Spectroscopy was also examined to attain the selective and sensitive optical sensor, and the trial sensing system was developed. Gold nanoparticles were also used for the nano-reporter particle, which were coupled with organic nano-fiber conductor. The sensitivity of the coupled sensor was higher than ordinal plasmonic sensors and could be addressed with optical method, which can be utilized for the odor space measurement.
