Fraunhofer Research Institution for Individualized and Cell-Based Medical EngineeringCustom magnetic particle spectroscopy: High-sensitivity nanoparticle characterization in real time
About
The Custom Magnetic Particle Spectrometer (MPS) is a precision instrument designed for the characterization of magnetic nanoparticles in liquid/solid media. It provides detailed analysis of particle size, magnetic properties, and concentration by measuring dynamic magnetic responses. Tailored to specific research or industrial needs, the system enables high-sensitivity, non-destructive, real-time measurements. Ideal for biomedical, environmental, and material science applications, this custom MPS supports advanced nanoparticle development, quality control, and functional performance evaluation under varying magnetic field conditions.
Opportunity
Different MPS applications require customized solutions, primarily based on factors such as excitation frequency, the strength of AC and DC magnetic fields, and the size of the measurement chamber. To address these varying needs, multiple configurations of the MPS system can be designed according to customer specifications.
Solution/Product description
MPS is a tool which is widely used in the characterization of different MNPs and can have different configurations depending upon the research goals. Primarily, an MPS device can be differentiated according to the excitation channels 1D, 2D and 3D excitation with or without a DC offset. The hardware can be customized according to the customer specification for the measurement chamber, excitation signal frequency, strength of the excitation field/ DC offset, filters, low noise amplifiers, software features etc.
