Plasmonic nanoparticles with chiral shape – PlaChiS

If chemists traditionally deals with chirality for organic molecular compounds, the community is more and more interested in plasmonic chiral nanostructures. Indeed, in addition to take part in fundamental understanding of chirality concept, studies of plasmonic chiral nanostructures leads to unique properties of materials with concrete and direct applications in the fields of catalysis, (bio)sensing, photonics… However, easily fabricating such nanostructures with a nanoscale chiral shape -ideally with an up-scalable, low cost, reproducible and versatile process- is currently a huge challenge. We want to address this challenge by developing a colloidal process for preparation of gold nanoparticles AuNPs with controlled chiral shape and high chiroptical properties (g-factor >0.1) tunable in the vis/NIR range, in high morphology yield and in large amount high for realistic future exploitation.
