中文摘要： 纳米科技的兴起颠覆了人们对传统材料的认识观，吸引了大量优秀科学家在介观尺度上的基础研究，各种新型材料不断地被开发出来。在这片崭新的领域里，超材料（Metamaterial）的研究是最引人注目也极具市场潜力的。超材料通常是一类在介观/宏观尺度上有规则重复结构的人工复合材料。取决于其人工结构而不是其组成材料的本征特性，超材料能获得自然界的天然物质所不具备的超常理化性质，譬如对微波雷达隐形等。近年来对超材料研究主要是集中在微波范围内超常电磁性质的获得，这很大程度上局限于材料加工能力，因为超材料的基元结构与电磁波波长要适度匹配。为了将类似工作原理的超材料延伸到短波段领域，譬如红外/可见波段，构造介观尺度上的基元结构至关重要。本课题的目的就是利用胶原蛋白在无机晶体上自组装的逆向生物矿化原理来构架新型的尺度可调的超材料骨架，并期待该新材料能取得突破，在红外/可见波段获得负折射率等超材料性能。

英文摘要： The rise of the nanotechnology has subverted our conventional concepts about materials and has been attracting numerous top scientists to conduct fundamental research on the mesoscale, which results in the successful development of many new functional materials. In this new filed, metamaterials are the most attractive ones and are of the best market potential as well. In general, metamaterials are the kind of artificial composite materials made of regular repeating units on the macroscale/mesocscale. Depending mostly on the structure of the repeating unit rather than the intrinsic quality of the constituent materials, metamaterials can possess unusual physical and chemical properties that do not naturally occur, such as microwave cloaking. In recent years, research on optical metamaterials was mostly focused on the unusual electromagnetic properties in the microwave region, which is largely limited to the material processing capacity. Because the size of repeating units of the metamaterials has to roughly match the wavelength of the electromagnetic wave, it is extremely difficult to extend the same processing method in the microwave region to infrared/visible region. In such cases, it is crucial to construct repeating units of optical metamaterials on the mesoscale. The purpose of this project is to construct si
