In this paper, a Finite Element (FE) and scaled-up experimental modal analysis are employed to estimate the natural frequencies of individual spherical and ellipsoidal cells. It is apparent that the mechanical properties of the living cells and particularly the natural frequencies might be related to the health condition of cells, and therefore a comprehensive analysis is carried out to determine the natural frequencies of individual cells. The natural frequencies and corresponding mode shapes are determined using COMSOL software for specific type of cell whose elastic properties of cell have been measured experimentally. To validate the numerical analysis, an experimental set up is designed to measure the natural frequencies of some scaled up models of cell. In parallel, the numerical method which is used for modal analysis of cell is employed to determine the natural frequencies of scaled up models of cell to show the agreement between the FE and experimental analyses.
