| Biopolymer particles |
Silica-fortified magnetic dextran nanoparticles (nanomag® -silica)
- 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
- a diameter of 250 nm and a magnetite content of 75-80%
- can easily be separated with a conventional permanent magnet
- designed with the surface functionalities OH (plain), NH2 and COOH for the covalent binding of proteins, antibodies or other molecules
- available with the hydrophobic octadecyl (C18) surface especially for nucleic acid separation
