Cellulose-based helical micro/nano filaments and films
If you have a question about this talk, please contact Sharon Connor.
Helical micro/nano filaments are ubiquitous in plants at various scales ranging from tendrils with millimeter diameters to micro helices existing in plants tracheary elements . Multilayered cellulose-based helicoidal structures were also found in certain fruits being responsible for their iridescent colors . Inspired by these helical structures filaments with intrinsic curvature  and cellulose-based structures that can reflect both left and right circularly polarized light  are presented. In this work we also discuss how the helical configuration of micro/nano elastic filaments and cellulose-based nanostructures can be precisely shaped.
