Biophysical mechanisms underlying the effects of static magnetic fields on biological systems

Abstract

Overview

With the increasing use of static magnetic fields (SMFs) in medical applications, understanding their biological impacts is of utmost importance.

Findings

• The study notes that magnetic materials within cells might influence various biological processes such as stress responses, proliferation, and structural alignment.
• Although SMFs are generally considered safe at the organ and organism levels, strong SMFs have been associated with adverse side effects in human subjects.
• The review suggests that the influence of SMFs involves various mechanisms such as the induction of electric fields and currents, generation of magnetic effects, and impacts on electron spins.
• Magnetomechanical effects noted include the orientation of biological samples when exposed to SMFs and movement in strong magnetic field gradients.
• Electrolytes flowing in a static magnetic field generate induced currents and electric fields, potentially affecting biochemical reaction rates and yields.

Conclusion

This study enhances understanding of how to exploit the beneficial biological effects of SMFs while being mindful of the associated health risks.
