DESCRIPTION:Helical micro/nano filaments are ubiquitous in plants at vario
 us scales ranging from tendrils with millimeter diameters to micro helices
  existing in plants tracheary elements [1]. Multilayered cellulose-based h
 elicoidal structures were also found in certain fruits being responsible f
 or their iridescent colors [2]. Inspired by these helical structures filam
 ents with intrinsic curvature [3] and cellulose-based structures that can 
 reflect both left and right circularly polarized light [4] are presented. 
 In this work we also discuss how the helical configuration of micro/nano e
 lastic filaments and cellulose-based nanostructures can be precisely shape
