Cellular Uptake of Magnetic Nanoparticles Quantified by Magnetic Particle Spectroscopy

The quantification of magnetic iron oxide nanoparticles in biological systems (cells, tissues and organs) is of vital importance in the development of novel biomedical applications such as magnetofection, drug targeting or hyperthermia. Among several techniques established to detect iron in tissue, the recently developed technique of magnetic particle spectroscopy (MPS) provides signals that are s...
