Perspectives

MATERIALS SCIENCE:
Smart Biomaterials

Daniel G. Anderson, Jason A. Burdick, Robert Langer

Advances in chemistry, cell biology, and materials science are fueling the production of smart biomaterials that are even smarter. As Anderson et al. describe in their Perspective, such smart biomaterials are revolutionizing the design of medical devices and drug delivery systems. Gone are the days when medical devices had to be manufactured from off-the-shelf materials such as polyetherurethanes, the material originally used to make ladies' girdles.
