Trapping of Magnetic Nanoparticles in the Blood Stream under the Influence of a Magnetic Field [2022-12-13]
Magnetic nanoparticles, as controlled drug carriers, provide tremendous opportunities in treating a variety of tumors and brain diseases. In this theoretical study, we used magnetic nanoparticles, such as Superparamagnetic Iron Oxide Nanoparticles (Fe3O4) (SPION). Due to their biocompatibility and stability, these particles represent a unique nanoplatform with a great potential for the development of drug delivery systems. This allows them to be used in medicine for targeted drug delivery, in magnetic resonance imaging and magnetic hyperthermia. In the work, the trapping mechanisms of magnetic nanoparticles moving in a viscous fluid (blood) in a static magnetic field are numerically studied. The equations of motion for particles in the flow are governed by a combination of magnetic equations for the permanent magnet field and the Navier–Stokes equations for fluid (blood). These equations were solved numerically using the COMSOL Multiphysics® Modeling Software. |
Numerical Simulation of Blood Flow in a Vessel by Using COMSOL Multiphysics® Software [2022-12-13]
Dynamics of the blood flow play an important role in the development and treatment of cardiovascular diseases. In recent decades, blood flow simulation has been widely used to better understand the symptomatic spectrum of different diseases, in order to improve existing or develop new therapeutic techniques. Numerical simulation for biomagnetic fluid (such as blood) flow through a tube with rectangular cross section under the influence of magnetic field is studied in this work. Blood considered as a magnetic and incompressible fluid. The magnetic field effects on the blood stream in a tube are created by a permanent magnet outside the tube. The equations of motion which describe the flow is governed by the combination of magnetic equations for permanent magnet and Navier-Stokes equation for fluid (blood) were solved numerically by using COMSOL Multiphysics® Modeling Software. |
