- Researchers at Tufts University developed a fluid silk material inspired by Spider-Man's web-shooting ability.
- The silk material is derived from moth cocoons, processed into fibroin protein, and can solidify mid-air when exposed to solvents.
- An accidental discovery involving dopamine significantly sped up the silk's solidification process.
- A coaxial needle system was created to shoot the silk solution, which solidifies upon contact with acetone and can adhere to objects.
- Adding chitosan and a borate buffer enhanced the silk's tensile strength and stickiness.
- The artificial silk can lift objects over 80 times its own weight, though it's still much weaker than natural spider silk.
- The innovation is described as 'superhero-inspired' rather than bio-inspired, showcasing its unique capabilities.
- Potential applications include various technological fields, with further improvements expected.
