Enhancement of electromagnetic freezing by stabilization and oscillation of biogenic magnetite particles |
摘要 |
Novel methods and systems for electromagnetic freezing are disclosed. An oscillating magnetic field can be applied in conjunction with a static magnetic field in order to align magnetic particles inside biological tissues. Such chains may be naturally present or artificially introduced. Needle-shaped electrodes may be used to produce ions and disturb the air layers insulating the tissues to be frozen. |

1. A system to freeze biological tissues, the system comprising:
a) a container, configured to contain biological tissues; b) a static magnetic field generator, configured to apply a static magnetic field to the biological tissues in the container; c) an oscillating magnetic field generator, configured to apply an oscillating magnetic field to the biological tissues in the container; d) a freezing element, configured to freeze the biological tissues in the container; and e) at least one electrode configured to apply a voltage to the biological tissues inside the container, the at least one electrode having a shape of a needle and being configured to produce ions at an air boundary layer adjacent to a surface of the biological tissues in the container. |
