TLDR
The first example of particles synthesized by direct emulsification of polypeptides found to display spiral morphologies in the dry state is reported, involving fibril bundling of coiled α-helices.Abstract:
Helical structures are ubiquitous in biological materials and often serve a structural purpose. Bioinspired helical materials can be challenging to synthesize and rarely reach the degree of hierarc...read more

Supramolecular Chiral Nanoarchitectonics.
TL;DR: Amplification of chiral molecular information from molecules to materials-level structures and the creation of chirality from achiral components upon temporal statistic fluctuations are universal, regardless of the nature of the assemblies and are thus surely advantageous characteristics for a wide range of applications.
