Magnosphere

Magnosphere™ is magnetic microparticles which can be used for life science research and in vitro diagnostic use. Available are two different type of surface characteristics; hydrophilic (MS) and hydrophobic (MX), and both chemically functionalized products and Bio-functionalized products.

Magnosphere™ particles are characterized by:

  • Uniform particle size
  • Core-shell structure
  • Good magnetic response
  • Good re-dispersability
  • Diverse surface chemistries
