That headline may need a little explaining so suffice to say, silk has a few more uses than you might expect from your favourite shirt and your least favourite bedsheets; namely the material is being used as a preservative barrier against spoilage for the transporting of blood samples.
Tutfts University bioengineer David Kaplan has developed a use for silk cocoons to store blood samples at room or body temperature while keeping them from spoilage or contamination. They take silkworm cocoons, hollow them out, boil them down and use them as little capsules for storage and transport.
Silk has several exciting properties which make this process possible. Of course, the strength and durability of silk has been known for centuries, but more interesting than that is the barrier it provides against infection or deterioration, meaning that for all our gadgets and gizmos, 21st century science still goes back to the silkworm for its medical breakthroughs.
