Silk emerges as important medical engineering polymer


One of the most promising polymers for medical applications is one of the oldest known materials to man: silk, which was used in ancient China and Europe.

In a study published this summer in the Proceedings of the National Academy of Sciences, researchers at Tufts University report a method to maintain the potency of vaccines and other drugs that otherwise require refrigeration for months and possibly years at temperatures above 110ºF, by stabilizing them in a silk protein made from silkworm cocoons.

Late last year the Tufts group announced development of a silk-based microneedle system able to deliver precise amounts of drugs over time also without need for refrigeration....
