Magnetic Controllability in Magnetic Nanogels — •Ivan Novikau1 and Sofia Kantorovich1,2 — 1University of Vienna, Vienna, Austria — 2Ekaterinburg, Russia
Magnetic Nanogels (MNGs) have emerged as versatile soft materials, especially promising for biomedicine due to the bio-compatibility of external magnetic fields. Recent research has focused on incorporating magnetic nanoparticles (MNPs) into nanogels for targeted drug delivery, enhanced uptake by tumor cells, and advancements in medical imaging and therapy.
This study utilizes molecular dynamics (MD) simulations and the Lattice-Boltzmann (LB) scheme to investigate the magnetic controllability of MNGs. Specifically, we explore the effective transfer of MNP torque to the polymer matrix, providing insights into guiding MNGs through the circulatory system.
For the suspensions of MNGs we calculate the magnetic susceptibility, and analyse the influence of an external magnetic field on viscoelastic properties, with a specific focus on the dynamic moduli.
