论文摘要
已知接近零磁场（称为次磁场）会影响生物学现象，包括发育过程，昼夜节律系统，神经元和脑活动，DNA甲基化，细胞中的钙平衡等等。但是，由于相应的能量远小于热能量，因此这种效果的确切机制仍然难以捉摸。众所周知，涉及自由基对的化学反应可能是在非常低的强度下与地磁场相当或小的磁场。在这里，我们从自由基对机制的角度详细审查了低磁场的效应，指出在某些条件下，它们比增加磁场的效果可能是可比甚至更强的。我们建议低磁场效应是测试生物学中自由基机制的有趣途径。
Near-zero magnetic fields, called hypomagnetic fields, are known to impact biological phenomena, including developmental processes, the circadian system, neuronal and brain activities, DNA methylation, calcium balance in cells, and many more. However, the exact mechanism underlying such effects is still elusive, as the corresponding energies are far smaller than thermal energies. It is known that chemical reactions involving radical pairs can be magnetic field dependent at very low intensities comparable to or less than the geomagnetic field. Here, we review in detail hypomagnetic field effects from the perspective of the radical pair mechanism, pointing out that under certain conditions, they can be comparable or even stronger than the effects of increasing the magnetic field. We suggest that hypomagnetic field effects are an interesting avenue for testing the radical pair mechanism in biology.
