Abstract
A substrate is described that is suitable for surface enhanced optical detection. The substrate comprises an electrically conductive layer The substrate further comprises at least one nanoparticle comprising an electrically conductive portion. The electrically conductive portion may provide an opening to an underlying material. Such at least one nanoparticles may be a nanoring, a nanodisc, or a non-spherical nanoshell. The substrate further comprises a dielectric spacer for spacing the electrically conductive layer from the at least one nanoparticles. The dielectric spacer is a dielectric material substantially only present under the at least one nanoparticle, leaving the electrically conductive layer uncovered from dielectric material at positions away from the nanoparticles. The at least one nanoparticle and the dielectric spacer are interfaced along a first major surface and the at least one nanoparticle comprises an upstanding surface not in line with an upstanding surface of the dielectric spacer.
