INDEX: Design to Improve Life®

Biodegradable polymers that are safe to use in the human body are already used in drug delivery, tissue engineering, and more. Whether impregnated with medicine or serving as a scaffold for growing cells, such polymers are eventually absorbed by the body when their work is done. Until now, however, none of these polymers has had the defining property of a rubber band: the ability to stretch then snap back to an original shape.

“Biorubber,” a new material with myriad applications including engineered lungs, heart valves and other elastic tissues. Biodegradable polymers that are safe to use in the human body are already used in drug delivery, tissue engineering, and more. Whether impregnated with medicine or serving as a scaffold for growing cells, such polymers are eventually absorbed by the body when their work is done.

In addition to being strong, biocompatible and inexpensive (because the researchers can make it in large quantities of some 400 grams per batch), biorubber also has a number of other advantages. For example, due to its general chemical composition it can be easily tailored to have a variety of different properties, such as a fast or slow degradation rate, for different applications. Biorubber’s brittle counterparts are much more difficult to modify.

Because of the physical characteristics of the material, it could act as scaffolding to help in the design of heart tissue, blood vessels, cartilage, bone and many other structures of the human body including whole organs for transplantation.
