Successfully artificially succeeded in producing spider threads, realizing a long-standing dream of scientists

ByAndrew Reding

The spider's string which is stronger than steel but has biodegradability even though it is lightweight was a material difficult to artificially produce because it contains special chemicals. Because spiders can produce only a small amount of yarn, artificially producing massive spider threads was a dream that scientists were pursuing for years but the research team of Swedish Agricultural Science University and Karolinska Institute, We succeeded in creating an artificial spider thread with a length of 1 km by a method that imitated the spider's production process for the first time.

Spider threadSilk glandIt has been made from an aqueous solution of protein stored in the secretory gland such as that it was difficult to obtain water soluble spider silk protein from other organisms and bacteria. Meanwhile, the spider itself was also considered to be a material that artificial production was difficult because it can produce only a small amount of spider threads, but the Swedish research team has been producing natural spider thread called "biomimetic spinning process" We have established a manufacturing method of "artificial spider thread" that imitated the method.


International academic journal ·Nature Chemical BiologyAccording to the contents announced in the spider silk gland inside the exquisite to store spider thread proteinProton gradientIt is said that the specific influence appears in spider thread protein because it is adjusted to. The research team succeeded in developing a spider silk production tool that imitated the spider silk gland, reported that artificial spider silk protein could be stored as an aqueous solution concentrated protein as well as natural, making processing possible doing.


The research team believes that "artificial spider threads will be used for biomaterials or special textile applications in the future". In addition, Japanese bio venture company ·SpiberHas completed the artificial protein fiber "QMONOS" made with the spider's yarn as a concept, the outer jacket made in QMONOS from the outdoor maker THE NORTH FACE "THE MOON PARKAWe are planning to release the product.
