Gabriele Giancane, Simona Bettini and Ludovico Valli introduce the Nanoscale Advances themed collection on Supramolecular chirality in self-organised systems and thin films.

Multicomponent chiral plasmonic hybrid nanomaterials with integrated multifunctionality exhibit intriguing chiroptical properties and promising applications in many interdisciplinary fields.

Helical modulators improve the operational stability of perovskite solar cells without a significant effect on photovoltaic characteristics, challenging the role of chiral interfacial modulators in hybrid perovskite photovoltaics.

Semiconductor quantum dots showing controlled circularly polarized luminescence were achieved through co-assembling with chiral peptide dendron gelator in water.

An enantioselective array comprised of chiral silica nanohelices grafted with porphyrins shows the capability of recognizing enantiomers with high classification accuracies.

The hybrid hydrogel of nanofibrous chiral supramolecular assemblies with sulfated polyethylene glycol exhibited self-healing property at a temperature below the gel-to-liquid crystalline phase transition of chiral assemblies.

Nanoconfinement on the fly impacts the alignment and chirality of self-assembled molecular networks.

Chiraltube, an accessible Python code, generates atomic coordinates of chiral nanotubes derived from the unit cell of any 2D material. These structures can then be used for further study using other visualization, simulation or calculation software.

In this work the role of catalysts in SWCNT chirality selection is considered via optimization of chemisorption strength between the carbon species and the catalyst surface needed to achieve stable nucleation and fast growth rates.

Chirality variation is clearly revealed in surface Ullmann coupling from self-assembly to graphene nanoribbons with staggered valleys.

We characterize the optical response of hollow WS₂ pyramids, that exhibit a strongly reduced photoluminescence with respect to horizontally layered WS₂. Studying the position dependence of the spectral Raman features reveals local variations in the atomic arrangement.
