Scientists at Tufts University have developed a breakthrough material—a fluid that transforms into a strong, sticky fiber, reminiscent of Spider-Man’s web-slinging abilities. This new technology can lift objects many times its own weight and could have various practical applications.
Inspired by the silk produced by insects like spiders and moths, researchers have long sought to replicate its unique properties. However, creating a material that matches spider silk’s strength and flexibility proved challenging—until now. In their study, published in Advanced Functional Materials, the team utilized silk moth protein, fibroin, combined with specific additives to produce a tough, adhesive fiber.

The process was accelerated by introducing dopamine, which quickly solidified the silk solution into sticky threads. As the fluid was shot through a specially designed needle, a thin layer of acetone helped it form a durable fiber that adhered to surfaces as the acetone evaporated. By adding chitosan and borate buffer, the researchers enhanced the fibers’ strength and adhesive qualities.
These sticky fibers can be adjusted in thickness and have shown the ability to lift objects over 80 times their weight. During tests, they lifted items such as a steel bolt, a lab tube, and a wooden block from a distance. While the strength of spider silk is still unmatched, this new invention marks a significant step forward in creating superhero-inspired materials for real-world use.
