Spider-Man-inspired sticky silk fibers lift 80 times their weight | The first web-slinging technology in which a fluid material shot from a needle solidifies – and is strong enough to adhere to and pick up objects.
It’s straight out of a comic book: a shot of liquid silk quickly hardens into a sticky, strong fiber that can lift objects 80 times heavier. Sound familiar? Researchers have described the Spider-Man-inspired tech in a new study.
It’s straight out of a comic book: a shot of liquid silk quickly hardens into a sticky, strong fiber that can lift objects 80 times heavier. “I was working on a project making extremely strong adhesives using silk fibroin, and while I was cleaning my glassware with acetone, I noticed a web-like material forming on the bottom of the glass,” said Marco Lo Presti, research assistant professor at Tufts and the lead author on the study. The researchers successfully picked up a cocoon, a steel bolt, a laboratory tube floating on water, a scalpel half-buried in sand, and a wood block from a distance of about 12 cm (4.7 in).
