An anonymous reader writes: A research and development effort by the University of Notre Dame, the University of Wyoming, and Kraig Biocraft Laboratories, Inc. has succeeded in producing transgenic silkworms capable of spinning artificial spider silks.
“This research represents a significant breakthrough in the development of superior silk fibers for both medical and non-medical applications,” said Malcolm J. Fraser Jr., a Notre Dame professor of biological sciences. “The generation of silk fibers having the properties of spider silks has been one of the important goals in materials science.â
Until this breakthrough, only very small quantities of artificial spider silk had ever been produced in laboratories, but there was no commercially viable way to produce and spin these artificial silk proteins. Kraig Biocraft believed these limitations could be overcome by using recombinant DNA to develop a bio-technological approach for the production of silk fibers with a much broader range of physical properties or with pre-determined properties, optimized for specific biomedical or other applications.
