- Аннотация: Any existing method of visualization of magnetic nanoparticles in biological objects provides for imposing of an external magnetic field on the object under study. The field can considerably change the space distribution and properties of the nanomagnetic ensemble under study. In our work a SQUID-based magnetoencephalography device was used for the measurement of a magnetic noise generated by superparamagnetic nanoparticles based ferrofluid in the stationary standing vial without imposing of an external magnetic field. It was demonstrated that the ferrofluid generates spontaneous magnetic fields sufficient for its localization inside the experimental setup. Besides it was revealed that the spontaneous magnetic fields at certain frequencies have a strong spatial anisotropy. The detected effect can essentially increase the spatial resolution of the proposed method of visualization of magnetic nanoparticles in biological objects without using the external magnetic field.
