Abstract

A computational model is developed to simulate the indentation of nucleus with a sharp probe, representing atomic force microscopy (AFM) with conical (sharp) tip. The nucleus model consists of two parts: (i) the nucleoplasm and (ii) the membrane layer representing the nuclear envelope. The nucleoplasm is modeled as a viscoelastic Maxwell material and the nuclear membrane layer is modeled as linear elastic. The overall model is employed to study the mechanical response of the nucleus to various time-dependent indentation loads, and examine the induced stress/strain patterns with different material properties for the nucleus and membrane layer.
