Magnetic Particle Imaging (MPI) is a new imaging method that relies on the harmonic response of magnetic nanoparticles to external, oscillating magnetic fields. The emergence of MPI has placed an emphasis on the ability to detect, characterize and distinguish magnetic nanoparticles in different environments, but conventional bore-type spectrometers limit the physical dimensions of nanoparticle sample holders and the environment in which the samples can be measured. This compact, single-sided spectrometer provides an alternative to conventional spectrometers, allowing nanoparticle detection from arbitrary sample holders.
