In nature, spider silk is a magical material that can create super strong fabrics. So why no one wants to build a "spider silk farm"? Perhaps it is too difficult for spiders to "cooperate", and labor has been difficult to achieve.
Technological development · artificial spider silk
In order to solve this problem, many laboratories have tried artificial spider silk, and even considered transferring spider DNA into silkworm.
The good news is that, through unremitting efforts, scientists have finally created a new machine that will take us a step closer to the future of textile materials.
The spider's secret is to secrete a protein solution through a narrow tube that, when it passes through the tube, presses it together to create a spider silk fiber.
Advantages and limitations
According to a recent study published in the journal Nature Chemicals, the researchers designed a similar machine that combines two natural spider silk proteins.
With this machine, the researchers have produced the strongest artificial spider silk to date. Its traits are almost identical to real spider silk, biodegradable, and relatively inexpensive to manufacture.
The way in which silk fiber is extracted through sericulture for thousands of years is expected to change in the future.
However, the progress made today does not mean that it can be put into mass production very quickly, because only one machine is currently built, and the scientists only spun about 1 kilometer of material. Therefore, large-scale production still needs to wait.
Researchers at the Brazilian Institute of Genetic Resources and Biotechnology have recently succeeded in producing artificial spider silk in the laboratory, which they believe is a scientific research product with high commercial value.
According to the researchers of the project, the spider silk protein required for this experiment was synthesized in the laboratory by means of E. coli.
Researchers dilute E. coli in a liquid medium to synthesize spider silk proteins with specific DNA sequences, and then use a special syringe to obtain protein fibers.
The artificial spider silk made by this method has a diameter of about 40 nm, which is 10 to 20 times thicker than the natural spider silk. In the future, researchers will also test the ductility and toughness of this artificial spider silk.
Elibio, a biotechnology expert who presided over the experimental project, said that the artificial spider silk not only has the advantages of good elasticity and toughness, but also biodegradable. It is expected to be applied in the fields of textile materials, medical and aircraft manufacturing in the future. .
