High-frequency electric field and radiation characteristics of cellular microtubule network.

摘要: Abstract Microtubules are important structures in the cytoskeleton, which organizes cell. Since microtubules electrically polar, certain microtubule normal vibration modes efficiently generate oscillating electric field. This field may be for intracellular organization and intercellular interaction. There experiments indicate electrodynamic activity of variety cells frequency region from kHz to GHz, expecting source this activity. In paper, results calculation intensity radiated electromagnetic power whole cellular network presented. The subunits (tubulin heterodimers) approximated by elementary dipoles. Mechanical oscillation is represented spatial function modulates dipole moment subunits. around calculated as a vector superposition contributions all modulated dipoles comprise network. radiation characteristics have not been theoretically analyzed before. For perspective experimental studies, that macroscopic detection system (antenna) suitable measurement radiofrequency since rate single very low (lower than 10−20 W). Low noise nanoscopic methods with high resolution enable cell vicinity desirable order measure reliably.
