identification of nano -scale mechanical properties of bio tissues by means of a novel nanoindentation technique

the mechanical characterization of bio tissues and other biological materials is of the most importance in clinical medicine and the field of biomaterials however there is not enough of information respecting the role of tissue mechanics in disease progression tissue repair and remodeling mechanisms associated with medical treatments tissues are challenging class of materials as they are composed of hierarchical structures with important features down to the nanometer or micrometer scale . nanoindentation has recently emerged as a powerful tool for measuring nano -and micro scale mechanical properties in bio tissues.
