Imagerie chimique des matériaux biologiques anciens

Abstract : Among archaeological materials, human remains as mummy skin bear precious and specific witness of ancient burial practices and lifestyles. They also give access to informations about degradations processes of biological tissues over a very long time scale.Chemical imaging, especially using cluster TOF-SIMS imaging, was applied to analyze complex hybrid materials. Using other analytical methods as a complement (SEM-EDX, FT-IR, DRX) this study could precise the structure and composition of human skin microsamples, from artificial and natural mummies. To achieve it, the crucial sample preparation step should be optimized.To understand the degradation processes, particularly proteic ones, ancient and modern biological tissues of similar composition (bones, horns, wool, silk, hair) were also analyzed.Our work could thus emphasize the benefit of TOF-SIMS imaging to understand mummification and degradation processes of tissues during centuries.
