Synthesis and characterization of magnetic iron oxide nanoparticles

Focus: 
Nanometrology

New diagnostic tools for medical applications and bioanalysis can be realized by magnetic nanoparticles from iron oxide.

By suitable functionalization with antibodies they can be employed as markers for proteins of all kinds. The magnetic nanoparticles are used in solution and have to be protected against corrosion. Therefore, the nanoparticles are enclosed in a non-magnetic layer. This layer ensures a minimum distance between the nanoparticles and prevents their aggregation. Precise control of this protection layer of only a few atomic monolayers thickness as well as of the diameter of the magnetic core of the nanoparticle is desirable. Both can be characterized precisely and fast by our new Magnetic Nanoparticle Analyzer.

The work contributes to characterization and theoretical description of the physical and biochemical properties of magnetic nanoparticles for biomedical applications.
