“…In particular, the static magnetic field of significant induction ( ) inhibits the DNA synthesis in mice, therefore, suppressing the tumor growth and even affecting the normal tissues, for example, decreasing the amount of blood cells 2 . On the other hand, the inhibition of apoptosis by the magnetic field can cause an increase in the risk of cancer development 3 , 4 . However, the latter effect is often considered to be related to the reactive oxygen species production rather than DNA synthesis 4 .…”

The rate of a chemical reaction can be sensitive to the isotope composition of the reactants, which provides also for the sensitivity of such “spin-sensitive” reactions to the external magnetic field. Here we demonstrate the effect of the external magnetic field on the enzymatic DNA synthesis together with the effect of the spin-bearing magnesium ions ($$^{25}$$ 25 Mg). The rate of DNA synthesis monotonously decreased with the external magnetic field induction increasing in presence of zero-spin magnesium ions ($$^{24}$$ 24 Mg). On the contrary, in the presence of the spin-bearing magnesium ions, the dependence of the reaction rate on the magnetic field induction was non-monotonous and possess a distinct minimum at 80–100 mT. To describe the observed effect, we suggested a chemical scheme and biophysical mechanism considering a competition between Zeeman and Fermi interactions in the external magnetic field.

“…2 On the other hand, a static magnetic field can inhibit apoptosis, increasing the risk of cancer. 3,4 Besides that, a lowfrequency electromagnetic field can promote DNA fragmentation in human cells, 5 while a relatively weak static magnetic field of 0.2 T significantly affects the DNA synthesis rate. 6 These observations determine the fundamental importance of the interaction of the magnetic field with soft matter.…”

Triggering gel‐sol transition by weak magnetic field

The self‐assembly of small and always chiral molecules into fiber‐like structures is a mysterious process, as the physics underlying such self‐assembly is unclear. The energy necessary for this process exceeds the one provided by common dispersion interactions and hydrogen bonding. The recent results obtained by the scientific group of Prof. Naaman from the Weizmann Institute of Science fed light on the nature of forces providing for the self‐assembly of chiral molecules and attributed these forces to spin‐exchange interactions. Therefore, the self‐assembly of chiral molecules should be magneto‐sensitive. We found such sensitivity in solutions of trifluoroacetylated ‐amino alcohols, and the process was inhibited by the magnetic field when fibers grew on the surface of the substrate. On the contrary, in bulk, the self‐assembly was enhanced by the magnetic field and led to the formation of a dense gel, while no gelation was observed in the absence of the external magnetic field. The latter observations are the theme of this short report, aimed to declare the effect itself but not pretend to describe it in full.

The self-assembly of small molecules into fiber-like structures is a mysterious process as the physics underlying such self-assembly is not clear. The energy necessary for this process exceeds the one provided by common dispersion interactions and hydrogen bonding. The recent results obtained by the scientific group of Prof. Naaman for the Weizmann Institute of Science fed light on the nature of the forces providing for the self-assembly of chiral molecules and attributed these forces to the spin exchange interactions. Therefore, the self-assembly of chiral molecules should be magneto-sensitive. We found such sensitivity in solutions of trifluoroacetylated alpha-aminoalcohols, and the process was inhibited by the magnetic field when fibers grew on the surface of the substrate. On the contrary, in the bulk, the self-assembly was enhanced by the magnetic field and led to the formation of the dense gel, while no gelation was observed in the absence of the external magnetic field.
