Calculation of the Electromagnetic Field Around a Microtubule Author: D. Havelka, M. Cifra Conference/Journal: Acta Polytechnica Date published: 2009 Other: Volume ID: 49 , Issue ID: 2-3 , Word Count: 71 Microtubules are important structures in the cytoskeleton which organizes the cell. A single microtubule is composed of electrically polar structures, tubulin heterodimers, which have a strong electric dipole moment. Vibrations are expected to be generated in microtubules, thus tubulin heterodimers oscillate as electric dipoles. This gives rise to an electromagnetic field which is detected around the cells. We calculate here the electromagnetic field of microtubules if they are excited at 1 GHz.
