Title: Nanomechanical mapping of biological interfaces: recent advances and 3D frontiers
Nanoindentation is a powerful microscale technique for mapping microscale mechanical properties of heterogeneous surfaces, including biological interfaces. This talk is a brief introduction to nanoindentation, a technique newly available on the MSU campus, as well as some of its applications to biological and non-biological samples. Special focus is placed on microscale mechanical property heterogeneity and its relation to larger-scale tissue toughness. Lastly, the talk will introduce current projects where microscale 'damage volumes' from nanoindentation are evaluated in 3D. This damage mapping approach may offer critical insights into the timeline of post-traumatic osteoarthritis following knee injury.
