Magnetization response spectroscopy of superparamagnetic nanoparticles for magnetic particle imaging

Journal of Physics D: Applied Physics, 2009
Magnetic particle imaging (MPI) is a tomographic imaging modality sensitive to the spatial distribution of magnetic particles. The spectrometer, described in this paper, is capable of measuring the remagnetization spectrum of superparamagnetic nanoparticles. With this spectrometer the suitability of particles, for MPI, can be characterized. Furthermore,

Cellular Uptake of Magnetic Nanoparticles Quantified by Magnetic Particle Spectroscopy

IEEE Transactions on Magnetics, 2013
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 ...

Multi-spectral Magnetic Particle Spectroscopy for the investigation of particle mixtures

Journal of Magnetism and Magnetic Materials, 2019
Abstract Magnetic Particle Spectroscopy (MPS) records the non-linear response of magnetic nanoparticles (MNP) to large ac magnetic fields. It captures a harmonic spectrum for the characterization of MNP samples, especially in the context of Magnetic Particle Imaging (MPI).

Stem Cell Vitality Assessment Using Magnetic Particle Spectroscopy

IEEE Transactions on Magnetics, 2015
In the field of regenerative medicine, we focus on repairing damaged tissue using appropriate cells for therapy that have healing capacities, such as human mesenchymal stem cells (hMSCs). Tissue healing using stem cells will only be possible if the cells can be homed to their target. Beside cell homing at the targeted organ, assessing the cell vitality

Perspectives of Magnetic Particle Spectroscopy for Magnetic Nanoparticle Characterization

2012
Magnetic Particle Spectroscopy (MPS) has been used to estimate the performance of magnetic nanoparticles for Magnetic Particle Imaging. It was demonstrated that one can reconstruct the particles core size distribution from the measured MPS spectrum. However, using MPS as an analytical instrument for the characterization of magnetic nanoparticle samples

Temperature measurements using static field magnetic particle spectroscopy

2013 International Workshop on Magnetic Particle Imaging (IWMPI), 2013
Measuring nanoparticle temperature accurately is particularly important as it could be used in hyperthermia, and whereas with the previous version of MSB the large fields of the hyperthermia apparatus would have made temperature measurements very difficult, by decoupling using the perpendicular static field, measurements perpendicular to the large ...

Precision particle spectroscopy with microcalorimeters in magnetic fields

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2000
Abstract Specific experiments, from solid state to elementary particle physics, require use of high-resolution particle detection in magnetic fields. When carefully designed, low-temperature microcalorimeters provide excellent energy resolution and low threshold. First results of Si-based microcalorimeters using state-of-the art implantation and bulk
