Scientists use genetically modified spider silk to make super bulletproof clothing
through genetic modification, American scientists have created artificial spider silk, which is stronger than steel. This research breakthrough will breed stronger fabric fibers for bandages and bulletproof vests for burn patients. The fibers produced by transgenic silkworms contain spider silk protein with higher elasticity and ductility, which can better meet the medical needs
9 [resolution] transgenic silkworms were bred by Dr. Donald Jarvis of the University of Wyoming and colleagues, and can express spider gene sequences. For a long time, scientists have been genetically modifying bacteria, yeast, plants, insects and mammalian cells to obtain spider silk protein. Previously, scientists have also tried to combine spider silk protein with silkworm spit fiber to form artificial spider silk, but the yield is relatively low
with the help of the new technology developed by Jarvis and others, the final fiber strength is equal to that of spider silk, and exceeds that of silk at the same time. The findings were published in the proceedings of the National Academy of Sciences. Researchers said that factories can use silkworms to produce high-strength silk fibers containing spider silk protein
Jarvis said: "As a biomaterial, spider silk has great uses, but for example, under the impact load, large deformation, in addition to using natural methods, there are great obstacles to obtain spider silk. Therefore, it is necessary to develop an effective biotechnology means to improve the yield of spider silk fiber. The research results show that silkworms can be genetically modified, and Jinan assaying's analysis of the machinery industry produces synthetic silk fibers containing stable spider silk protein, The mechanical properties of this kind of fiber are far more active than silk fibers.
