Abstract

We used the Langmuir-Blodgett (LB) method for preparation of defect-free and large-area silica-nanoparticlesmonolayer as a template for the fabrication of Au nanostructures on an Au-thinfilm for surface plasmon resonance (SPR). The dimensions of trigonal pyramid Au nanostructures were controlled by changing the particle size of the silica LB template. The nanostructured SPR chips provide the enhancement of sensitivity in SPR analysis compared to a conventional SPR chip when 20 % ethanol solution was used as an analyte. We took a theoretical approach by evaluating optical properties of the Au-nanostructures and nanostructured SPR chips in the view of plasmonic effect.
