In this study, we fabricated "plasmonic membrane" which contructed with Au deposited polytetrafluoroethylene (PTFE) membrane filter for sensing application. By using this plasmonic membrane, Specific absorption peak based on LSPR could be observed in visible region. In addition, by introduction of solutions which has different refractive index, absorption peak intensity changes also could be observed.
From these results, this plasmonic crystal was successfully fabricated for sensing applications easily.
