Abstract


Detecting biomolecules such as proteins and studying their molecular structure functionality is crucially important for life-sciences. Infrared absorption spectroscopy is an important tool for functional studies of bio-molecules. Sensitivity limitations, however, hinders the applicability of the technique to single molecule/monolayer studies and also measurements in solutions. In this talk we will describe use of infrared plasmonic and metamaterial antennas to enable overcome many of these limitations. We will also show that use of plasmon hybridization and Fano-resonances in individually tailored antennas can be exploited to further extract information about proteins including their height and orientation.
