Nanoindentation of Biomaterials

Natural biomaterials have special structures and functions through the evolution of exchanging material, energy, and information with natural surroundings over millions of years (Tong et al. 2001). ™e quantitative measurement of the mechanical properties of natural biomaterials will help one to understand biological structures and biological functions of living things, and to develop bionic materials including bionic smart materials, advanced biomedical materials, and industrial materials. ™e development of the value-added transformation of agricultural biomass materials also needs the understanding of their structure and mechanical properties. ™e mechanical properties of a material in micro-and nanoscale are di£erent from those in macroscopic scales.
