德国拜罗伊特大学的研究人员研制出了一种韧性和弹性与蛛丝相当的人造纤维,解决了现有纤维弹性不足的问题,使制造更安全的气囊成为可能。研究人员将蜘蛛的造丝基因拼接到大肠杆菌中,使大肠杆菌得以在酒精和水的混合溶液中产生4种分子。随后,研究人员利用湿法纺丝方法拉长 Researchers at Bayreuth University in Germany have developed a man-made fiber with tenacity and elasticity comparable to those of spider silk, which has solved the existing problems of insufficient fiber elasticity and made it possible to manufacture safer airbags. Researchers spliced ​​filaments of spiders into E. coli, allowing E. coli to produce four molecules in a mixture of alcohol and water. Subsequently, the researchers lengthened using a wet-spinning method
