Characterisation and analysis methods

There exist many different analysis techniques of MNPs that take into account magnetic, material and structural properties. In the NanoMag project we will use both basic analysis techniques (that we will improve in order to extract optimum parameters for standardization and design of magnetic nanoparticles) as well as more application oriented analysis methods (where we also will improve the techniques and the used models). The analysis techniques that will be used in the NanoMag project are listed below.

  • DC magnetization and AC susceptometer analysis
  • Medium and high frequency AC susceptometry
  • Mössbauer spectroscopy 
  • Electron Microscopy 
  • XRD and SAXS 
  • SANS
  • Ferromagnetic resonance
  • Dynamic light scattering and Electrophoretic Light Scattering
  • Field-flow fractionation
  • Mass spectrometry
  • Magnetic modelling

We will also use more application oriented methods (that can also be used for bio-sensing application); 

  • Magnetorelaxometry 
  • Magnetic particle spectroscopy 
  • Magnetic particle rotation 
  • Magnetic separation 
  • NMR R1 and R2 relaxivities 
  • Magnetic nanoparticle bio-detection
  • Magnetic hyperthermia measurements 

In spite of the presence of many different analysis techniques, some of the analysis results are inconsistent (for instance concerning the magnetic dead-layer concept at the surface of magnetic nanocrystals, how the inter-particle interactions and effective magnetic anisotropy influences different types of analysis, etc) and have to be studied in detail. These are typical questions we will solve in the proposed NanoMag project. In the following text we will go through the above given analysis techniques in more detail.
