Method for the detection and / or identification of magnetic supraparticles by means of magnetic particle spectroscopy or magnetic particle imaging

摘要

The present invention relates to a method for the detection and / or identification of magnetic supraparticles by means of magnetic particle spectroscopy (MPS) or magnetic particle imaging (MPI), in which magnetic supraparticles are provided which each contain a large number of magnetic nanoparticles and a specific one Composition and / or structure, the magnetic supraparticles are exposed to at least one magnetic field, whereby depending on the magnetic moment of the magnetic supraparticles at least one voltage and / or a voltage curve is induced, the at least one voltage and / or the voltage curve being detected as at least one measurement signal is generated from the at least one measurement signal at least one spectrum which contains harmonics, each having an amplitude and a phase, and the magnetic supraparticles (unambiguously) detected and / or iden- tify using the at least one generated spectrum be verified.
