Abstract

The detection of biomolecules can be boosted by coupling them with field enhancing substrates such as plasmonic nanoantennas or photonics crystals. Many natural occurring molecules are chiral, thus detecting schemes have to discriminate from two opposite enantiomers. This can be obtained by suitable chiral substrate nanopatternig. Among different fabrication methods the self-assembly approach can lead to low cost, large area metasurfaces with desired functionalities. Here we present the optical circular dichroic behavior of some of these structures and possible applications.
