General description

Superparamagnetic iron oxide nanoparticles implanted in polymer microspheres are used in magnetic resonance imaging contrast enhancement, immunoassay, tissue repair, hyperthermia, detoxification of biological fluids, and drug delivery. Polystyrene microspheres (magnetic beads) are also widely used in cell separation and labeling.
Magnetic polystyrene particles

Application

Micro particles based on polystyrene, magnetic has been used in the preparation of poly(ethylene oxide) (PEO) solution and particles to study the viscoelastic focusing performance of the zigzag microchannel using both nonmagnetic particles and magnetic particles.
