Key aspects of activity
- Size- and shape-controlled synthesis of superparamagnetic iron oxide nanocrystals (SPIONs)
- Synthesis of cubic and octapod star-shaped iron oxide nanocrystals in the size range of 4-60 nm for cubic and 20-80 nm for octapod star-shaped NK based on the thermal decomposition of iron oleate
- Investigation of the reaction mechanism: elucidation of nucleation precursors and pyrolysis products by means of matrix-assisted laser desorption ionization with time-of-flight mass spectrometer detection (MALDI-TOF-MS)
- Functionalization and encapsulation of iron oxide nanocrystals by seed emulsion polymerization
- Targeted post-oxidation of SPIONs to increase saturation magnetization
- Characterization of SPIONs by Magnetic Particle Spectroscopy - development of a tracer for Magnetic Particle Imaging (MPI)
