| Outline of Final Research Achievements |
Localized surface plasmon resonance (LSPR) sensor was fabricated by immobilizing gold nanoparticles (AuNPs) on the surface of hetero-core fiber optic, and the sensor was applied to measure gasoline concentration in flex fuel that is a mixture of gasoline and bioethanol.
The spectra measured by using multichannel analyzer show a peak at 540nm, and the peak strength increased according to increasing of gasoline concentration. This result indicates that gasoline concentration in flex fuel could be measured by using this LSPR sensor. The propagating loss spectra varied by depositing layer-by layer thin film on the sensor surface. In case that porous glass beads were immobilizing and hydrophobized, the sensor characteristic was improved in the sensitivity and linearity in wide concentration range. Furthermore, the miniaturized measurement system was developed by using LED, PD and one-board data-processing substrate. The output had a good agreement with that of the multichannel analyzer.
