This in vitro study examined effects of moderate static magnetic field exposure on sympathetic neuron-like PC12 cells. The authors report a significant reduction in voltage-gated potassium (Kv) channel current density after 18 hours of exposure, with the reduction persisting after the field was removed. RNA sequencing identified 37 SMF-sensitive genes and pathway analyses suggested upregulation of signaling associated with reduced neuronal excitability.
Enhancement Effect of Static Magnetic Field on Bactericidal Activity
This in vitro study reports that a static magnetic field (SMF) combined with paramagnetic calcium-polypyrrole nanoparticles (Ca-PPy) markedly increases bactericidal activity against E. coli and S. aureus. The authors attribute the enhanced killing to increased reactive oxygen species generation and associated membrane disruption, with computational analysis suggesting altered radical-pair transitions under magnetic fields. The abstract frames SMF as potentially biocompatible and useful for bactericidal applications, while also noting broader biological impacts of electromagnetic fields.
