Soft matter : A new basic principle behind the cooperation among multiple functions in a dynamic hierarchical system

软物质最典型的特征之一（例如，聚合物、液晶和胶体）是其分级结构。最近的研究表明，即使是简单的液体也有类似的能级结构。预计这种层次结构的不同层次之间的复杂耦合在软物质和生物物质的功能的协同性中起着至关重要的作用。然而，到目前为止，很少有研究的流体动力学相互作用的作用，层间耦合和液体本身的水平结构如何影响软物质的功能。针对这些问题，阐明了软物质和生物物质所特有的多功能协同作用背后的一些基本物理原理。

One of the most characteristic features of soft matter (e.g., polymers, liquid crystals, and colloids) is its hierarchical structure. Recent studies indicate that even a simple liquid has a similar level structure. It is expected that complex couplings among the different levels of such a hierarchic structure play a crucial role in the cooperativity of functions of soft and bio matter. However, there have so far been few studies on the role of hydrodynamic interactions on inter-level couplings and how the level structure of a liquid itself affects functions of soft matter. Focusing on these problems, we elucidated a few basic physical principles behind the cooperation among multiple functions, which is unique to soft and bio matter.
