TL;DR: It is shown that DNA origami enables the high-yield production of plasmonic structures that contain nanoparticles arranged in nanometre-scale helices, and it is found that the structures in solution exhibit defined circular dichroism and optical rotatory dispersion effects at visible wavelengths that originate from the collective plAsmon–plasmon interactions of the nanoparticles positioned with an accuracy better than two nanometres.
