NATURAL CALCIFIED TISSUES

Our approach to the study of hard tissues from mammals (e.g., bone and teeth) and from other animals (e.g., shells and exoskeletons of crustaceans) is largely based on physical-chemistry characterization techniques. Among these techniques, Electron Microscopy (SEM and TEM), diffraction techniques, and more recently, Focused Ion Beam (FIB), have been providing answers to fundamental questions about the nature, origin, and function of these biological materials. Our current focus is on mineralized tissues from reptiles and fish.
