In Part 3, Langer focuses on the materials used in drug delivery and medical devices. Many of the original materials used in medicine were adapted from completely unrelated uses and often generated their own problems. Langer describes work by his lab and others to make polymers designed for specific medical uses. For instance, a porous polymer can be shaped into an ear or nose and act as a scaffold onto which a patient’s cells can be seeded to grow a new structure. Different polymers have been successfully used as scaffolds to grow new blood vessels or artificial skin for burn victims.
