Orb webs are fascinating feats of bioengineering in nature, displaying magnificent architectures while providing essential survival utility for spiders. The unusual combination of high strength and extensibility is a characteristic unavailable to date in synthetic materials yet is attained in nature with a relatively simple protein processed from water. This biological template suggests new directions to emulate in the pursuit of new high-performance, multifunctional materials generated with a green chemistry and processing approach. These bio-inspired and high-technology materials can lead to multifunctional material platforms that integrate with living systems for medical materials and a host of other applications. 摘要 蜘蛛或桑蚕生成的丝蛋白纤维，是力与美的结合体。从本质上而言，圆形蜘蛛网在生物工程上有着极好的功用，当作为蜘蛛赖以生存的工具时，它展现出了完美的力学构架。迄今为止，在合成材料领域中材料难以同时获得高强度和较好的延展性；而在天然材料中一种结构相对简单的蛋白质通过用水处理即可获得高的强度和较好的延展性。这给了我们一个新的效仿方向——通过绿色化学合成和加工的方法去获得一种新的、高性能的、多功能的材料。这些仿生和高科技材料能够在医药材料和一些其他的应用上使多功能材料平台和生命系统相结合起来。 M echanically, silks are outstanding material systems. The toughness of silk fibers is superior to any of the best synthetic high-performance fibers avail
