Simulation of Shape and Structure Response of Nonspherical Magnetosensitive Vesicles Subjected to Magnetic Fields

Molecular dynamics simulation is performed to study the coupled magnetic, structural, and mechanical response of magnetosensitive vesicles to quasi-static
on/off
switching of an external magnetic field. The vesicle membrane filled with magnetic nanoparticles is modeled in a coarse-grained bead-spring representation. In detail, it is shown how discocyte- and stomatocyte-like vesicles respond to the uniform magnetic field. Notably, having undergone an
on/off
switching cycle, a vesicle does not always restore in full its shape.
