Electric field generated by higher vibration modes of microtubule
Cifra, Michal ; Havelka, D. ; Kučera, Ondřej ; Pokorný, Jiří
Certain structures in a living cell may generate electric oscillations. Microtubules, which form a part of a cellular skeleton, belong to this class of structures and ful-fill all conditions for generation of electric oscillations in kHz÷GHz band. We present selected results from calculations of the oscillatory electric field generated by higher vibration modes of microtubules. We propose that the electric field of certain modes may play specific function in cellular organization
Calculation of the Electromagnetic Field Around Microtubule
Havelka, D. ; Cifra, Michal
Microtubules are important structures in cytoskeleton which organizes the cell. Single microtubule is composed of electrically polar structures, tubulin heterodimers, which have strong electric dipole moment. Vibrations are expected to be generated in microtubules, thus tubulin heterodimers as electric dipoles are oscillating. This gives rise to electromagnetic field, which is detected around the cells. We calculate here the electromagnetic field of microtubules if they are excited at 1 GHz. This paper includes the work done in bachelor thesis of the first author.
