Nanoscale Conical Swiss Roll with Broadband Visible and NIR Circular Dichroism

A new strategy based on dynamic shadowing growth is developed to fabricate Swiss roll chiral metamaterials in nano­scale. The fabricated Swiss roll nano­structures exhibit broadband circular dichroism response in visible to near-IR wavelength region. Importantly, this strategy allows the dimension of Swiss rolls to be easily tuned, which subsequently changes their chiral optical properties.
