From: Revealing the static and dynamic nanomechanical properties of diatom frustules—Nature's glass lace
In situ SEM nanoindentation of cleaned frustules and dried diatom cells. (a) SEM images of air-dried diatom cells measured by nanoindentation in the SEM column, (b) SEM images of cleaned frustules. Scale bar, 10 µm. (c) Force–displacement curves obtained during indentation of dried cells, (d) Calculated area under the force–displacement curves of dried and cleaned diatoms equal to work done, (e) The case of a layered structure of the frustules of some diatoms, potentially responsible for difference in the obtained force-distance curves. Video material corresponding to (a, b) is provided in Supplementary Materials (see Supplementary Videos 3–13).
