Cracking a Tooth
January 12, 2011
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 3-D map of the location and identity of millions of individual atoms in the complex hybrid material that allows the animal to literally chew rock.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering.
