Key Properties

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

Why use Magnosphere?

  • Core Shell Structure & Uniform Bead Size

    Magnosphere™ magnetic beads consist of a core particle, a magnetite layer and a surface polymer layer. Controlled size of the core particle ensures uniform particle size.



  • Various Surface Designs

  • Surface Structure Properties




  • No Iron Oxide Exposure

    Magnetic particles were incubated with o-phenylenediamine (OPD) and H202. OPD coloring was measured to estimate the influence of iron oxide exposure on the immunoassay.



  • Optimal Performance
