Magnetic polystyrene beads that we can offer are: embedding type and core shell type. The former is prepared by embedding magnetic nanoparticles(Fe3O4 nanoparticles) in monodisperse polystyrene microspheres and the later is by coating a thin layer of iron oxide onto uniform polystyrene microspheres.
By chemical modification, magnetic polystyrene microspheres can link with various functional groups as well as special antibody, protein, and nucleic acid which make magnetic polystyrene microspheres widely used in the industries of cell separation, protein purification, and immunoassays.
Magnetic Polystyrene Beads-Core shell type
The suspension of core shell type magnetic polystyrene microspheres are brown. The structure of core shell type is with monodisperse polystyrene microspheres coated by a thin layer of magnetic nanoparticles(Fe3O4). The dispersant is phosphate buffer. It has good mono dispersity and magnetic response. Sedimentation will happen after long time unused. Before use, shake or ultrasonic dispersion is suggested.
- Superparamagnetic behavior
- Extremely narrow size distribution
- 0.1um-2um monodisperese magnetic polystyrene microspheres are available.
