Stronger engineered spider silk created
August 9th, 2021
A Spun polymeric amyloid fiber. Photo: Jingyao Li. Spider silk is said to be one of the strongest, toughest materials on earth. Now engineers at Washington University in St. Louis have designed amyloid silk hybrid proteins and produced them in engineered bacteria. The resulting fibers are even stronger and tougher than some natural spider silks. […]

Hybrid silkworms spinning larger cocoons
April 27th, 2018
Kraig Biocraft Laboratories Inc. recently announced the first production of recombinant spider silk cocoons from the new line of hybrid transgenic silkworms created at its Michigan production and research facility. The new line was created by combining one of Kraig Biocraft’s best performing recombinant spider silk lines with a commercial strain, resulting in the largest […]
Enhanced silk as strong as carbon fiber developed
October 5th, 2017
Scientists led by Nicola Pugno at Italy's University of Trento have combined spider silk with graphene and carbon nanotubes, producing a composite material five times stronger. Innovation Textiles reports that silk incorporating graphene and carbon nanotubes is produced by spider spinning, after feeding spiders with water containing the nanotubes. Although only produced on a small […]
Researchers spin spider silk one kilometer long
January 18th, 2017
Spider silk characteristics make it attractive for a wide variety of uses: It is stronger than steel, is tolerated well when implanted in tissue and it’s biodegradable. Harvesting the silk, however, has proven a hurdle. Spiders are difficult to keep captive, needless to say, and they produce small amounts of silk. Large-scale production requires artificial […]
Utah State shares spider silk research contract award
December 18th, 2015
Utah State University has announced that it has been awarded a U.S. Army Small Business Innovation Research Phase II contract with Salt Lake City based Technology Holding LLC to continue research and development of spider silk manufacturing. The total contract award is $1 million and is managed through the Army Research Office. Under the terms […]
Kraig Biocraft Labs close to prototyping Monster Silk™
September 10th, 2013
Kraig Biocraft Laboratories Inc., developer of advanced spider silk-based fibers, announces that its pilot production program has successfully produced a sufficient quantity of Monster Silk™ cocoons to allow it to make its first textile prototypes. The cocoons still need to be reeled and processed into yarn before the first prototype and sample textiles can be […]
