Two MSE Professors Chad Mirkin Now Elected Elected to American Academy to All Three Branches of the of Arts and Sciences National Academies

orthwestern University scientist Chad A. Mirkin, a world- renowned leader in nanotechnology research and its application, Nhas been elected a member of the prestigious Institute of Medicine (IOM). He is the first at Northwestern and in the Midwest and the 10th in the world to be elected to all three branches of the National Academies. Mirkin was elected a member of the National Academy of Sciences earlier this year and a member of the National Academy of Engineering in 2009. Mirkin is the George B. Rathmann Professor of Chemistry in the Weinberg New AAAS inductees David Seidman and Monica Olvera de la Cruz.

eeth and bone are important and com- plex structures in humans and other T animals, but little is actually known about their chemical structure at the atomic scale. What exactly gives them their renowned toughness, hardness and strength? How do or- ganisms control the synthesis of these advanced functional composites? Now, using a highly sophisticated atomic- scale imaging tool on a sea creature’s tooth, two Northwestern University researchers have peeled away some of the mystery of organic/ inorganic interfaces that are at the heart of tooth and bone structure. They are the first to produce a three-dimensional map of the location and identity of millions of individual atoms in the complex hybrid material that allows the animal to literally chew rock.
