nanomag®-silica

Silica-fortified magnetic dextran nanoparticles (nanomag®-silica)

  • are prepared via the core-shell method with a core of magnetite and a dextran shell with a simultaneous cross-linking of the dextran strands by silica nanostructures,
  • have a diameter of 250 nm and a magnetite content of 75-80%,
  • can easily be separated with a conventional permanent magnet,
  • are designed with the surface functionalities OH (plain), NH2 and COOH for the covalent binding of proteins, antibodies or other molecules,
  • are available with the hydrophobic octadecyl (C18) surface especially for nucleic acid separation.
