It is well established, that plasmonic oscillations in metal nanorods efficiently enhance near-field under resonant conditions. In the infrared, fundamental antenna-like resonance can be used for surface-enhanced infrared spectroscopic (SEIRS) studies. In the project NANOANTENNA we optimize such system for application of SEIRS to the detection of rare biomolecular disease indicators in the human blood. Accordingly, as first step, a biocompatible material combination was identified and secondly, the resonance condition is optimized.
