Magnetorelaxometry of magnetic nanoparticles with fluxgate magnetometers for the analysis of biological targets

Abstract: A magnetorelaxometry system based on sensitive fluxgate magnetometers for the analysis of the relaxation behavior of magnetic nanoparticles is presented. The system is tested with a dilution series of magnetite. The results are directly compared with data obtained with a SQUID magnetorelaxometry system measured on the same samples. Advantages of using fluxgates rather than SQUIDs for magnetorelaxometry are discussed. [Copyright &y& Elsevier]
