Abstract Scope Tooth enamel is the most highly mineralized and hardest tissue of the body, and a potent source of bio-inspiration. At the nanometer scale, it is comprised of hydroxyapatite nanocrystals (cross section ~50x150 nm) separated from each other by a nano-scale layer of amorphous mineral and organic residues. At the micro-scale, thousands of nanocrystals are bundled together into rods, which are separated from their neighbors by a few tens of nm of interrod nanocrystals. Despite the basic understanding of the fundamental microstructure, there has been rather limited advancement in understanding the arrangement of crystals and composition at the nanoscale. We have recently applied laser pulse atom probe tomography (APT) to study the compositional distribution in enamel at the level of nanocrystals and changes associated with age. We have also adopted synchrotron nanoscopic computed tomography (s-nCT) to explore enamel rod morphology at the nanoscale. Details of these findings will be presented.
