We study metallic nanoparticles arranged in chiral structures, with the aim of enhancing the inherently weak chiral light-matter interaction, whether in absorption, fluorescence, or Raman optical activity. Our goal is to gain an improved physical understanding of how light interacts with chiral structures at the nanoscale, and conversely, how nanostructures can shape the polarisation of local electromagnetic fields. This research combines spectroscopic experiments and numerical modelling to explore a broad range of fundamental questions on novel chiroptical effects, as well as direct the development of future applications in molecular detection.
