Abstract:

The last two decades have witnessed tremendous activity in the field of plasmonics. This huge interest originates from the ability of confining light at sub-nanometer length scales exploiting collective electronic excitations of metallic nanostructures, known as surface plasmons.

In this seminar, I will discuss recent advances in the fabrication of plasmonic materials. The first case focuses on the interrogation of collective plasmonic oscillations in gold nanorod supercrystals, and demonstrates the potential of plasmonics as an alternative technique for imaging biomolecules in undisturbed biological samples. The second part of the seminar focuses on the in situ synthesis of plasmonic nanostructures combining both microfluidics and soft-lithographic approaches, and their potential role for the creation, development, and application of new tools for the understanding of light-matter interaction in the weak- and strong-coupling regime.
