Spiders?

How are spiders involved in your process?

No spiders are harmed in the making of Bolt Threads Microsilk® fibers! In fact, there are no spiders at all in the process. We originally studied real spiders’ silk to understand the relationship between the spiders’ DNA and the characteristics of the fibers they make. Today’s technology allows us to make those proteins without using spiders—which is a big relief to the arachnophobes among us.
