Liquid‐crystalline dispersions of cellulose nanocrystals mediate the self‐assembly of plasmonic nanoparticles. By imposing nematic‐like and helicoidal ordering on the spatial organization of anisotropic metal nanoparticles, mesostructured composites with novel properties such as polarization‐dependent surface plasmon resonance are obtained by I. I. Smalyuk and co‐workers on page 7178. Obtained using crossed polarizers and a retardation plate, the optical image depicts drops with gold nanorods mimicking order in the liquid‐crystalline matrix of cellulose nanocrystals.
