Double Bouligand Printed Twisted Stacks: Mirrored Chiroptical Polarization and Enhanced Compressive Mechanics

open access: yesAdvanced Optical Materials, EarlyView.
This work demonstrates the production of nature‐inspired double Bouligand structures via shear‐aligning cellulose nanocrystals for comparison against more commonly studied single Bouligand architecture. Optical and mechanical analysis shows retained chiroptical polarization and increased mechanical integrity under compression elucidated with ...

Biogenic Next‐Gen CPL Emitters: Strategies with Proteins, Polysaccharides, and Nucleotides

open access: yesAdvanced Optical Materials, EarlyView.
Biogenic molecules such as proteins, peptides, saccharides, and DNA can act as natural scaffolds for generating circularly polarized luminescence (CPL). This review highlights recent strategies exploiting these inherently chiral frameworks to achieve light emission with controllable handedness under unpolarized excitation, bridging biological ...

Could Edible Photonic Structures Be an Alternative to Traditional Food Coloring?

open access: yesAdvanced Optical Materials, EarlyView.
What if color in food came from photonic structures? This perspective introduces structural color as a potential next‐generation solution to replace conventional colorants in foods. It discusses edible photonic materials, their unique benefits, and the technological, safety, and consumer acceptance challenges that must be addressed to bring this ...
