A novel-shaped plasmonic chiral nanomaterial exhibiting circular dichroism in the near infrared spectral range is presented. Applying on-edge lithography, a large area with these nanostructures is efficiently covered. This fabrication method offers tunability of the operation bandwidth by tailoring the chiral shape.
