Abstract

Many physical processes that take place in human and animal hemoglobin are associated with a transport of minerals, air, charge carriers, ions, and spin. They are greatly influenced by external electric and magnetic fields, the concentration of mineral intake, pH value, thermal conditions, and the structure of hemoglobin. In this research, emphasis is given to spin transport in hemoglobin, where a weak spin transport is noticed. In order to clarify the nature of spin transport, the magnetic states are first identified. Then, by developing spin diffusion equations, we investigate the spin diffusion transport in the hemoglobin. This transport is associated with the transition of spin from the high-spin state (deoxyhemoglobin) to the low-spin state (oxygenated hemoglobin). The spin transition is caused by oxygen binding to the heme, resulting in heme–heme interaction of cooperative binding. Hence, the effect of magnetic fields, concentrations, and pH on spin transport is visualized. The spin diffusion transport is then compared with the nature of billiards and ballistic transport in hemoglobin. Whence, factors hindering the spin transport along the Fe-N magnetically easy axis are explored. Then the significant roles of myoglobin (Mgb), in carrying oxygen, spin transport, and as a medium spin generator are demystified. Then, the impact of Fe concentrations and Fe-N magnetic easy axis on the transport process is visualized. Finally, the biophysical properties of hemoglobin and the potential role of spin transport in maintaining metabolic processes and biomedical engineering are envisioned.

Keywords: Ballistic transports, billiard transport, charge carriers, hemoglobin, spin
