General description
Magnetic polystyrene particles
Superparamagnetic nanoparticles embedded in polystyrene microspheres (magnetic beads) play a vital role in cell separation and labeling. In addition, it is also used in various biomedical and bioengineering applications such as magnetic resonance imaging contrast enhancement, tissue repair, immunoassay, detoxification of biological fluids, hyperthermia, and drug delivery.
Application
Micro particles based on polystyrene, magnetic has been used as magnetic biofilm carriers to separate and re-introduce microorganisms in a continuously stirred tank reactors (CSTR). It has also been used in magnetic microrheometry for measuring the cell-size-scale viscoelastic properties of stiffer 3D cell-culture matrices by micromanipulator experiments.
