Successful imaging of the atomic structure of shark teeth
Successful imaging of the atomic structure of shark teeth
Elucidation on how fluorine affects strong teeth
-Joint research by Tohoku University, the University of Tokyo, and the Tokyo Medical and Dental University-
Summary
A joint research group led by Professor Yuichi Ikuhara (Joint Appointment as Professor, University of Tokyo) and Research Assistant Chunlin Chen of the Advanced Institute for Materials Research (WPI-AIMR) at Tohoku University, and Professor Yoshiro Takane of the Research Center for Medical and Dental Sciences at Tokyo Medical and Dental University utilized the world's most advanced ultra-high resolution scanning transmission electron microscope and succeeded in the direct imaging of the atomic structure of shark enamel for the first time in the world. This substance, fluorapatite, is found on the surface of shark teeth and is known to be the hardest biological material.
