Design and Simulation of a 3D Actuation System for Magnetic Nano-Particles Delivery System
نویسندگان
چکیده
In this paper, a new electromagnetic actuation system is presented for magnetic nano-particles based targeted drug delivery. The system is composed of three sets of coils; each set contains two parallel coils that can generate the oriented 3D magnetic gradient field. Differential Current Coil approach is used to calculate the applied current to each coil to ensure that the gradient field, generated in region of interest, is permanently higher than the value needed for saturation of magnetic particles. To investigate the performance of the actuation system, a simulation model, relating to magnetic field distribution and the trajectories of the magnetic particles, has been studied using finite element approach. The proposed actuation system is very compact and cheaper as compare to the previous system and the simulation results showed that this actuation system can be used effectively for nano-particles based drug delivery systems.
