perimag®
Dextran based magnetic nanoparticles (perimag®)
- exhibit excellent properties as contrast agents for Magnetic Resonance Imaging (MRI) and Magnetic Particle Imaging (MPI) (Eberbeck et al. 2013, Konkle et al. 2015 and Zheng et al. 2016),
- are suitable for homing and tracking of stem cells in regenerative medicine as well as for hyperthermia applications (Kilian et al. 2016),
- are prepared by precipitation of iron oxide in the presence of dextran,
- are available with a particle diameter of 130 nm,
- cannot be separated with a conventional permanent magnet but in a high gradient magnetic field,
- are designed with the surface functionalities OH (plain), NH2 and COOH for the covalent binding of proteins, antibodies or other molecules (Drews et al. 2013),
- are available with covalently bound streptavidin for the binding of biotinylated molecules,
- can be manufactured with higher iron concentration upon request.
