The mollusc shell is composed of microscopic layers of tabular calcium carbonate crystals and thin sheets of proteins with precise nanoscale architectures. This configuration produces a high-performance composite material that exceeds the present capabilities of human engineering. This integrated study will elucidate the molecular mechanisms controlling the fabrication of these architectures. This knowledge will contribute significantly to the development of materials for advanced electronics and energy transducers, human bone therapeutics and marine?based products such as pearls and cements, through the identification of genes underlying biofabrication networks and the development of in vitro bioproduction systems.

这种软体动物的外壳是由碳酸钙晶体的微观层和具有精确纳米结构的蛋白质薄片组成的。 这种配置产生了一种高性能的复合材料，超过了人类工程的现有能力。这项综合研究将阐明控制这些架构制造的分子机制。这些知识将大大有助于先进的电子和能源传感器，人体骨骼治疗和海洋材料的发展？通过鉴定生物制造网络的基因和开发体外生物生产系统，我们可以为珍珠和水泥等基础产品的生产提供技术支持。
