Two Dimensions Simulation of a Magnetotactic Bacteria Cell Exposed to an Electromagnetic Field at 3 GHz

Abstract

Abstract The effect of the presence of magnetite nanoparticles inside biological objects when they are exposed to microwaves has not yet been investigated completely. Microwaves magnetic hyperthermia is a field under development, and the use of biogenic magnetite is a relatively new vista. In this regard, the present approach presents a first step in a modeling-simulation process focused on the computation of the absorbed power distribution in bacteria cells containing native magnetite nanoparticles in the form of chains (magnetosomes). The presented simulations’ results refer to the simplest case of two-dimensional computation, which doesn’t take into consideration the geometric and magnetic anisotropy characteristics of the real magnetosomes.
