How is Young's Modulus Measured in Biological Tissues?
Several techniques are employed to measure Young's Modulus in biological tissues:
Atomic Force Microscopy (AFM): AFM can measure the mechanical properties of tissues at the nanoscale, providing high-resolution stiffness maps. Nanoindentation: This technique involves indenting a material with a known force and measuring the resulting displacement to calculate Young's Modulus. Magnetic Resonance Elastography (MRE): MRE uses MRI technology to visualize and measure the mechanical properties of tissues in vivo. Tensile Testing: This traditional method involves stretching a tissue sample and measuring the stress-strain response.
