Dynamic mechanical properties of soft tissues localized by fluorescence microscope obtained using nanoindentation
2012
Abstract
The paper deals with an assessment of material characteristics of particular substructure of soft tissues their transition by mean of fluorescence nanoindentation. Ten millimeter thick plates of native lumbar spine motion segments were dissected from sagittaly halved porcine spine. 7-10 mu m sections were cut in an angle of 45 degrees to transversal plane using a microtome.
They were stained with hematoxylin-eosin afterwards. We obtained dependancies of storage and loss moduli on the frequency range 5-200 Hz.
Damping trends and viscosity were discussed in this paper as well.
