Аннотация:
The possibility of non-invasive detection of magnetic particles in biological objects using magnetic field sensors of various types is investigated. Estimates of the threshold sensitivity of the sensors and the maximum distance at which the sensor can detect magnetic particles are made. It is shown that magnetite particles with a concentration of ∼ 10-9 vol.[%], superparamagnetic particles and catalytic particles of the composition "iron in carbon nanotubes" can be fixed by SQUID or combined magnetic field sensors with operating temperatures ∼ 4 K at a distance of ≤ 0.1 m. It is noted that magnetic field sensors with ultra-low threshold sensitivity values (≤ 10-10 T) may be promising for non-invasive control of organs, implants, prostheses and other elements of biological systems. © 2019 Published under licence by IOP Publishing Ltd.
