Dextran based magnetic nanoparticles (synomag®-D)

• Are core-shell particles with a maghemite core that has a "NanoFlower" structure surrounded by a dextran shell,
• Show excellent properties as a tracer for magnetic particle imaging and are suitable for hyperthermia applications,
• Are available with hydrodynamic diameters of 50 nm and 70 nm,
• Cannot be separated with conventional permanent magnets, but only in a high gradient magnetic field,
• Are offered with the surface groups OH (plain), COOH, PEG-COOH, NH2 and PEG-NH2 for the covalent binding of proteins, antibodies and other molecules,
• Are available with PEG-OMe (25 kDa) on the surface for increased circulation time in the blood,
• Are available with covalently bound streptavidin for binding biotinylated molecules or with biotin on the surface for binding streptavidin derivatives.
