Abstract
The cytoskeleton, especially microtubules, is potential source of electrodynamic field of living eukaryote cells. Microtubule network is a very dynamic structure which is composed of highly polar molecules - tubulin heterodimers. Microtubules have their eigenmode vibrations in frequency range from kHz to GHz. We approximated electrical properties of tubulin heterodimer as an elementary electric dipole and described the longitudinal mechanical oscillation of one microtubule by spatial modulation function. Mechanical oscillations of tubulin heterodimers were approximated as a chain of rigid particles and described by the spatial modulation function. An optical branch was used as it is more efficient for generation of electromagnetic field. We also created asymmetrical model of microtubule network of dividing cell and symmetrical model of microtubule network of non-dividing cell. The field around oscillating microtubule was calculated as a vector sum of contributions from all elementary electric dipoles. Finally, we performed calculations with several cell sizes and numbers of microtubules in models and performed comparative analysis.
