Behind the secrets of silk lie high-tech opportunities
Date:7/29/2010

MEDFORD/SOMERVILLE, Mass. -- Tougher than a bullet-proof vest yet synonymous with beauty and luxury, silk fibers are a masterpiece of nature whose remarkable properties have yet to be fully replicated in the laboratory.

Thanks to their amazing mechanical properties as well as their looks, silk fibers have been important materials in textiles, medical sutures, and even armor for 5,000 years.

Silk spun by spiders and silk worms combines high strength and extensibility. This one-two punch is unmatched by synthetics, even though silk is made from a relatively simple protein processed from water.

But in recent years scientists have begun to unravel the secrets of silk.

In the July 30, 2010, issue of the journal Science, Tufts biomedical engineering researchers Fiorenzo Omenetto, Ph.D., and David Kaplan, Ph.D., report that "Silk-based materials have been transformed in just the past decade from the commodity textile world to a growing web of applications in more high technology directions."

Fundamental discoveries into how silk fibers are made have shown that chemistry, molecular biology and biophysics all play a role in the process. These discoveries have provided the basis for a new generation of applications for silk materials, from medical devices and drug delivery to electronics.

Edible Optics, Implantable Electronics

The Science paper notes that the development of silk hydrogels, films, fibers and sponges is making possible advances in photonics and optics, nanotechnology, electronics, adhesives and microfluidics, as well as engineering of bone and ligaments. Because silk fiber formation does not rely on complex or toxic chemistries, such materials are biologically and environmentally friendly, even able to integrate with living systems.

Down the silk road of the future, Kaplan and Omenetto believe applications could include degradable and flexible electroni
