Journal ArticleDOI
Pointillist structural color in Pollia fruit
Silvia Vignolini,Paula J. Rudall,Alice Rowland,Alison Reed,Edwige Moyroud,Robert B. Faden,Jeremy J. Baumberg,Beverley J. Glover,Ullrich Steiner +8 more
TL;DR: It is demonstrated that animals and plants have convergently evolved multilayer-based photonic structures to generate colors using entirely distinct materials.
Journal ArticleDOI
The Self-Assembly of Cellulose Nanocrystals: Hierarchical Design of Visual Appearance.
Richard M. Parker,Giulia Guidetti,Cyan A. Williams,Tianheng H. Zhao,Aurimas Narkevicius,Silvia Vignolini,Bruno Frka-Petesic +6 more
TL;DR: The mechanisms underlying the formation of iridescent, vividly colored materials from colloidal liquid crystal suspensions of cellulose nanocrystals are reviewed and recent advances in structural control over the hierarchical assembly process are reported as a toolbox for the design of sophisticated optical materials.
Journal ArticleDOI
Biomimetic layer-by-layer assembly of artificial nacre
Alexander S. Finnemore,Pedro Cunha,Tamaryn A. V. Shean,Silvia Vignolini,Stefan Guldin,Michelle L. Oyen,Ullrich Steiner +6 more
TL;DR: This is the first successful attempt to replicate nacre, using CaCO(3), and presents a route to artificial nacre that mimics the natural layer-by-layer approach to fabricate a hierarchical crystalline multilayer material.
Journal ArticleDOI
A 3D optical metamaterial made by self-assembly
Silvia Vignolini,Nataliya A. Yufa,Pedro Cunha,Stefan Guldin,Ilia Rushkin,Morgan Stefik,Kahyun Hur,Ulrich Wiesner,Jeremy J. Baumberg,Ullrich Steiner +9 more
TL;DR: A 3D optical metamaterial, based on the replication of a self-assembled block copolymer into gold, is demonstrated, which has a feature size that is two orders of magnitude smaller than the wavelength of visible light.
Journal ArticleDOI
Block copolymer self-assembly for nanophotonics
TL;DR: Recent advances on photonic architectures derived from block copolymers are reviewed and the influence and complexity of processing pathways are highlighted to predict expanded photonic capabilities and limits of these approaches in light of future developments of the field.
