Patent round-up: Sea cucumber corneas - tech - 05 November 2007 - New Scientist Tech

http://technology.newscientist.com/channel/tech/dn12878-patent-roundup-sea-cucumber-corneas.html?feedId=online-news_rss20 --- The team's artificial cornea is made from tiny collagen fibres extracted from these sea cucumbers. When placed in a centrifuge, the fibres self assemble into layers in which the fibres are aligned vertically, a structure that is very similar to the tissue in mammalian corneas. The result is a thin layer of material that is transparent and biocompatible, as well as cheap and easy to make, says the team.
