Microscopic heterogeneity in viscoelastic properties of molecular assembled systems

摘要: An important step in understanding molecular assembled systems is to examine the structure and physical properties at various length scales clarify correlation between them. However, while structures of these have been extensively studied from nanoscopic macroscopic scales, their viscoelastic often limited bulk rheological measurements. By using optical tweezers particle tracking, we here show local spatial distributions for following systems: worm-like micelle solution, supramolecular hydrogel lyotropic liquid crystal, which are formed by self-assembly amphiphilic molecules water. We found that all possessed a heterogeneity this was originated heterogeneous structures. It interesting note there with characteristic scale sub-micrometer or micrometer scale, thereby structures, although nanometer size. The findings studies should lead better dynamics such systems.
