Abstract
We show how nacre and pearl construction in bivalve and gastropod molluscs can be understood in terms of successive processes of controlled self-assembly from the molecular- to the macro-scale. This dynamics involves the physics of the formation of both solid and liquid crystals and of membranes and fluids to produce a nanostructured hierarchically constructed biological composite of polysaccharides, proteins and mineral, whose mechanical properties far surpass those of its component parts.
摘要
我们展示了如何从分子尺度到宏观尺度的连续可控自组装过程来理解双壳类和腹足类软体动物中珍珠层和珍珠的形成。这种动力学涉及固体和液晶、膜和流体形成的物理学，以产生一种由多糖、蛋白质和矿物质组成的具有纳米结构的分层构建的生物复合材料，其机械性能远远超过其组成部分。
