On the parallel simulation of magnetic targeting of nanoparticles in capillaries

Abstract

We develop a parallel algorithm, by using CUDA, for calculating the concentration of multifunctional magnetic nanoparticles in capillaries under the influences of magnetic force, blood flow and diffusion process. The task of computing particle, concentration on the considered plane is distributed to computational threads. The continuity equation describing the time rate of change of the multifunctional particle concentration in each small element on the considered plane is solved via the explicit finite different method. The simulation results show the distributions of particle concentration on the focused plane in the blood vessel which are useful visualization for the biomedical researchers. The performance of parallel computing is also examined.
