    Sammanfattning : Magnetic measurements of the Brownian relaxation time of thermally blocked magnetic nanoparticles dispersed in a solution have been performed in order to determine the hydrodynamic size distribution of the particles. By measuring changes in the hydrodynamic size of the particles, the ammount of analytes attached to the surface of particles can be determined. LÄS MER
