Paper Abstract

We recently proposed an alternative elasticity measurement technique based on elastic wave propagation within a single cell. Waves are capture using an ultrafast camera and a microscope. This technique is based on the local measurement of the speed vs of a shear wave, a type of elastic wave. By assuming an infinite and homogeneous elastic medium with respect to the wavelength, the shear modulus μ (elasticity) is estimated. These latter assumptions are discussed through experiments conducted in controlled elastic solids. The conclusion is that wave guide effects as well as viscosity are crucial for quantitative mapping of elasticity.
