要約(英語): The localized surface plasmon resonance (LSPR)-based plasmonic chemical sensor for detection of aldehyde compounds was developed using gold-capped nanoparticle layer substrate. In this study, for detection of aldehyde compounds, 2-Nonenal which some research has associated with human body odor alterations during aging was choose as a target. For detection of 2-Nonenal, self-assembled monolayer (SAM) was formed on the gold-capped nanoparticle layer substrate surface using 2-Aminoethanethiol. The LSPR absorbance changes by the surrounding refractive index change that is attributed by the covalent binding between aldehyde group of 2-Nonenal and amino groups of 2-Aminoethanethiol were monitored. By using this chemical sensor, the LSPR absorbance change with 2-Nonenal concentrations could be observed.
