Characterizing in situ poroelastic properties of cytoplasm by the translation of a rigid spherical inclusion

Biomechanics in “Sino-Italian Joint”

“…Determination of the poroelasticity of the cytoplasm is challenging, as its material behaviors are usually rate-and size-dependent, mainly caused by diffusion of free molecules and deformation of cytoskeleton. Based on the theory of the translation of a rigid spherical inclusion, Sun et al [3] proposed a new method for the characterization of the poroelasticity, providing a powerful tool for in situ measurement of material properties of cytoplasm via optical/magnetic tweezers.…”
