Orb spider silk, already among the toughest and strongest materials found in nature, could soon get a super-strong nanoscale upgrade. A research team from the University of Trento, Italy recently sprayed 15 Orb-weaving spiders, members of the Pholcidae family, with carbon nanotube or graphene particle solutions. They found that doing so caused some of the spiders to spin even stronger silk than what they normally do. The team administered five spiders with a graphene-water solution and another 10 with a carbon-water mix. While some spiders subsequently spun sub-par silk (and four of them died outright), a few of the carbon-dosed arachnids actually produced strands 3.5 times stronger than the most resilient natural silk we know about.
