Spider silk belongs to the toughest fibres in nature and has astounding properties. Scientists from the University of Würzburg discovered new molecular details of self-assembly of a spider silk fibre protein. They are lightweight, almost invisible, highly extensible and strong, and of course biodegradable: the threads spiders use to build their webs. In fact, spider silk belongs to the toughest fibres in nature. Based on its low weight it even supersedes high-tech threads like Kevlar or Carbon. Its unique combination of strength and extensibility renders it in particular attractive for industry. Whether in aviation industry, textile industry, or medicine - potential applications of this magnificent material are manifold.
