Special Issue Information

Dear Colleagues,

Since the mid-20th century, extensive empirical research has demonstrated that magnetic fields can influence living organisms in diverse and sometimes unexpected ways. While the mechanisms that promote the effects of strong magnetic fields are well understood, the biophysical basis for the action of weak alternating fields whose energies lie below thermal noise and static fields comparable to the geomagnetic field on plants and animals remains unknown. This area of research offers exciting opportunities for discovery, with the potential to unlock novel approaches to modulating and controlling biological systems.

This Special Issue welcomes contributions that explore the biological effects of magnetic fields at all levels of organization, from molecular mechanisms to population-level dynamics. We particularly welcome original research articles and comprehensive reviews that bridge the fields of physics, biology, and applied sciences.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biophysica is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The effects of static magnetic fields (SMFs) on fibroblast proliferation and migration remain debated, largely due to variability in field intensity, orientation, and exposure duration, as well as the predominant use of endpoint-based assays that may not fully capture the temporal dynamics of cellular responses. Thus, it remains unclear whether reported SMF effects reflect changes in proliferation, migration, or both. Here, we examined how SMFs with different field configurations affect NIH3T3 fibroblast behavior. Three setups were tested: a field generated by two neodymium magnets arranged in a face-to-face configuration on opposite sides of the culture dish (SMF1) and single-magnet setups with either the north (SMF2 and SMF2a) or south poles (SMF3 and SMF3a) facing the cells. SMF1 was associated with a 41% increase in proliferation relative to control, while single-cell migration velocities, directional persistence, and collective wound closure showed no detectable changes. In contrast, SMF2 and SMF3, as well as their low-field variants SMF2a and SMF3a, did not produce significant effects. Our results suggest that a specific SMF configuration is associated with increased fibroblast proliferation without detectable changes in migration parameters under the tested conditions. This integrative approach helps contextualize prior divergent findings by suggesting that SMF effects may be configuration-dependent, thereby contributing to a more rational application of magnetic stimulation in cellular and tissue engineering contexts.

The biological effects of weak low-frequency magnetic fields (LFMFs) remain controversial, particularly regarding frequency-specific resonance-like responses. Many previous studies tested different frequencies sequentially, potentially introducing uncontrolled environmental variability. This study aimed to evaluate frequency-dependent effects of LFMFs on the growth of juvenile Daphnia magna under strictly synchronized and temperature-controlled conditions. Genetically identical neonates from a single parthenogenetic brood were simultaneously exposed to sinusoidal 50 μT magnetic fields at 20, 25, 30, 35, or 40 Hz using spatially separated Helmholtz coils integrated into a closed-loop thermal stabilization system. Body length was measured after 48, 96, and 144 h of exposure. No significant growth differences were detected after 48 h. After 96 h, a significant biological effect was observed only at 30 Hz. The most pronounced responses occurred after 144 h, with significant growth stimulation at 25, 30, and 35 Hz and a maximal effect at 30 Hz. The frequency–response relationship exhibited a dome-shaped pattern that became less sharply peaked with prolonged exposure. These findings demonstrate duration-dependent and frequency-specific stimulation of juvenile daphnid growth with weak LFMFs. It suggests that exposure time critically influences the manifestation and breadth of resonance-like magnetobiological effects. Full article
