Twisting nanoparticles : Plasmonic circular dichroism was experimentally obtained in chiral 3D organizations of gold nanorods obtained by self‐assembly of the nanoantennas onto a fiber template with a twisted morphology. Numerical simulations based on coupled dipoles confirm the crucial role of gold nanorods in this intense circular dichroism.
