How a spider spins electrified nanosilk

There are some spiders that are trapping their prey with glue, while there are some other types, for example like the cribellate orb spider, who are using static electricity. In the Jan. 27 Biology letter, scientists has reported that this spider’s special spinning technique actually electrifies its nanoscale silk.

Researchers have collected these kinds of spider from the garden centers in England and then they have analyzed the images and videos of that whole spinning process. Later, the examined the silk samples by using more types of microscopy.

The tiny glands line the web-making apparatus on the belly of the spider produces a gooey, which is a raw silk substance called dope. Then – the funnels are transporting the dope to spigots and afterwards the silk solidifies as it shoots out of the spigot. And as the spiders comb and pull it into nanofibers, electrostatic friction is charging their threads.
