Abstract


A problem of optimal assembly from magnets modelling for steering of magnetic nanoparticles in a closed environment containing a stream of close-to-blood liquid is considered in this research. The targeting assembly from magnets is designed based on Halbach arrays and contains 18 permanent magnets forming a movable and a stationary block of the targeting part of a magnetic drug delivery device. The injected particles were diverted from their flow path near the vicinity of movable part of assembly from magnets while not aggregating thereat, but migrating to the target zone under the stationary part of the said assembly. Minimum magnetic force value was established for the injected particle path manipulation towards the target area.
