This work explores the fabrication of a chiral plasmonic metasurface using bottom-up DNA origami technology to achieve strong circular dichroism (CD). The optical properties of the chiral metamolecule — a tripod decorated with gold nanorods — were simulated and optimized with JCMsuite. The software enabled full-wave finite-element calculations to retrieve the T-matrix, compute orientation-averaged CD spectra, and assess the feasibility of the metasurface design.
