Micro and nano filaments are ubiquitous in Nature and vital not only to the living
systemsbut also to produce materials, which can be used in everyday life [1, 2].
The morphology presented by microfilaments is crucial to the way they interact
with the environment. For instance, it was found that chirality is an important
issue, which can determine the interactions between threads and their organization,
to form intricate fabrics and non-woven membranes [2].
In this presentation we focus on flexible elastic microfilaments behavior [2-4]and
in the determination of their outer surface structure [5].
This work open routes to the understanding of the relationships between the
structure/function of the microfilaments, which are critical for the packing of
natural tissues and fabrics.
