This Colloquium analyzes the interaction of light with two-dimensional periodic arrays of
particles and holes. The enhanced optical transmission observed in the latter and the …

Manipulating light on the nanoscale has become a central challenge in metadevices,
resonant surfaces, nanoscale optical sensors, and many more, and it is largely based on …

The potential of random metal-dielectric nanocomposites as constituent elements of
metamaterial structures is explored. Classical effective medium theories indicate that these …

Nanoporous (NP) materials have promising potential uses in energy storage, catalysis, and
high-radiation environments. However, wide application of NP materials—or other emerging …

An enhanced dielectric environment response is observed in a kind of metallic nanohole
arrays which are prepared by metal deposition on a sacrificial two dimensional colloidal …

We report that rhomb-shaped metal nanoantenna arrays support multiple plasmonic
resonances, making them favorable bio-sensing substrates. Besides the two localized …

We investigate nanostructured surfaces consisting of a hexagonal lattice of polymeric pillars
embedded in a gold matrix. These systems are prepared by a new fabrication technique …

Nanostructured nickel surfaces representing periodically arranged spherical voids in a
nickel film are obtained by electrochemical deposition through a self-assembled opaline …

Non-close packed (NCP) colloidal arrays find wide applications in the fields of photonics,
optical chip fabrication, nano sphere lithography and so on. However, unlike their close …

We report single molecule fluorescence studies on nanoporous gold films. We observed
dramatically enhanced intensities in individual immobilized fluorophores and reduced …
