Kraig Biocraft Laboratories, Inc. is a biotechnology company focused on the development of commercially significant high performance polymers and technical fibers. Based on proprietary genetic engineering technology, the company is working to develop and produce polymers and protein-based materials from silkworms and spiders. Kraig Biocraft believes that spider silk is a “super fiber” that will have numerous commercial and consumer applications.

Kraig Biocraft recently announced that scientists have discovered a way to make spider silk three times stronger by adding small amounts of metal. Even though the natural spider-made fiber is already tougher and lighter than steel, this new technique could make it useful for manufacturing super-tough textiles and high-tech medical materials, such as artificial bonds and tendons.

The discovery, published by the journal “Science”, was made by researcher Seung-Mo Lee of the Max Planck Institute of Microstructure Physics in Halle, Germany. The breakthrough addition of zinc, aluminum or titanium to a length of spider silk made it more resistant to breaking or deforming, effectively making the strand three times stronger.

Kraig Biocraft CEO Kim Thompson stated, “This new discovery is absolutely incredible. Spider silk is already known as one of the strongest fibers found in nature and is recognized for its unparalled capacity to absorb and dissipate energy in a very controlled manner. Being five times stronger than steel of the same diameter in its natural form, this enhancement reminds us again of the extraordinary potential spider silk has. Kraig Biocraft Laboratories is committed to continuing to develop sustainable spider silk for commercial use worldwide.”
