The formation mechanism of the hollow and helical fibers was proposed. During the heat treatment, the hollow fibers could be formed when the inner gel of the thinner precursor fibers was separated from the center and contracted to surface. However, the helical fibers could be generated when larger gel fibers were broken helically under thermal stress in the process of gel decomposing and contracting.

Scanning electron microscopy,transmission electron microscopy,circular dichroism and small-angle X-ray diffraction were used to analyze the aggregation mode of CSG in the organogel phase.A hierarchical self-assembly model was proposed to explain the transition from molecular to primary and secondary structure.It is shown from our results that CSG can aggregate into a micellar fibril nanostructure with high length-to-width ratio which is bundled and entangled to form a three-dimensional(3D) network that immobilize the fluid component probably by surface tension.Moreover,sol-gel polymerization of tetraethoxysilane was carried out using CSG in the gel phase.

It was demonstrated that the actin could be polymerized into discrete filaments of tree-like branch structure, random coil filaments cluster and long filaments with different diameters in F-buffer besides random aggregates. These polymerized filaments clearly exhibited the structural polymorphism and showed obvious difference from those assembled under the regulation by actin binding proteins or phalloidin.
