Paper Abstract

We present a three dimensional (3D) metallic nanostructure, which has transmission resonance properties related to both localized surface plasmons and propagating surface plasmon polaritons. Various geometrical dimensions of the 3D metallic nanostructures were studied by means of simulation and experiment with respect to resonance position, resonance line width and bulk sensitivity. Narrower resonance line width and higher bulk sensitivity were achieved for the 3D nanostructure compared to conventional nanohole arrays. Finally, a 3D metallic nanostructure functionalized with a biotinylated thiol could detect streptavidin, suggesting the device may have potential as a bio-sensor.
