Scientists claim to have developed a Spider-Man style silk adhesive made from moth cocoons.

The researchers from Tufts University's Silklab in Massachusetts said they utilised silk fibroin from moth cocoons to engineer a fluid material that can be shot from a needle.

It solidifies into strong, adhesive fibres mid-air, mimicking the comic book hero's ability to swing through cityscapes and capture adversaries.

The research added that the process involves a silk solution mixed with dopamine and other compounds, which rapidly transforms into a solid fibre when extruded through a needle and exposed to acetone.

They claimed that the fibre adheres to surfaces with remarkable tenacity and has the strength to lift objects more than 80 times its weight.

Research assistant professor Marco Lo Presti said it was an accidental discovery that happened while cleaning lab equipment. The team incorporated dopamine into the silk solution and then accelerated the solidification process, creating fibres with enhanced tensile strength and stickiness like Spider-Man's web.

Researchers said that it opens doors to numerous applications, from medical adhesives to sustainable materials for electronics.

The study's director, Fiorenzo Omenetto, said: 'We navigate the boundary between imagination and practice. That's where all the magic happens.'

Spider and moth silk have gained attention in recent years for their remarkable properties - particularly their strength - and potential applications in various industries.

Moth silk is prized for its smooth texture, luster, and natural insulating properties. It is used in luxury fabrics and even in medical textiles such as bandages, sutures, and drug delivery systems.

Further uses include tissue Engineering and implants as well as in cosmetics and as a replacement for plastic packaging.
