Visualizing chiral structures in cellulose nanocrystal films by a Mueller matrix microscope.

Visualizing chiral structures in solid materials is crucial but difficult in chiral analysis. The three-dimensional structures in the helicoidal nano-assemblies in cellulose nanocrystal (CNC) films were visualized using a Mueller matrix microscope (MMM). Optical analysis of the assembly of CNCs through structural reconstruction by optical simulation revealed the complex structures in CNC films.
