TL;DR: These Goldhelices based on inorganic templates are much more robust than previously reported organic-based chiroptical nanostructures, making them good candidates for complex hierarchical organization, providing a promising approach for light management and benefits in applications such as circular polarizers, chiral metamaterials, or chiral sensing in the visible range.

TL;DR: Results indicate that closely packed and helically arranged PNCs on silica nanohelices result in an increase of the optically active properties in the film state.

TL;DR: The optical properties of chiral artificial nano-photonic materials, Goldhelices, which are hierarchically organized by Grazing Incidence Spraying are described and the measured optical properties are discussed and compared to simulations.

TL;DR: In this paper, the authors explored the ability of ellipsometry to characterize colloidal suspensions composed of gold nanoparticle (NP) chains and derived the complex effective index of these suspensions from ellipsometric measurement by using a wavelength-by-wavelength inversion without any dispersion law.

TL;DR: In this article, a nanoscale control over the assembly of highly anisotropic silica helices using convective flow by using the physical properties occurring during evaporation-induced self-assembly is proposed.
