TL;DR: In this article, the authors proposed an approach for rapid and sensitive detection of SARS-CoV-2 with functionalized magnetic nanoparticles via the measurement of their magnetic response in an ac magnetic field.

TL;DR: In this paper, the effect of the alignment of the magnetic easy axes on the dynamic magnetization of immobilized magnetic nanoparticles under an AC excitation field was explored, and it was shown that the parallel-aligned sample has the largest hysteresis in the magnetization curve and the largest harmonic magnetization spectra.

TL;DR: A detailed signal generation of the magnetization response of magnetic nanoparticles (MNPs) as a result of externally applied magnetic fields with flux densities of several millitesla is of high in this paper.

TL;DR: In this article, a dual-frequency acquisition scheme was proposed to enhance sensitivity and contrast in the detection of different particle mobilities compared to a standard single-frequency MPI protocol, taking advantage of the fact that the magnetization response of the tracer is strongly frequency-dependent.

TL;DR: In this paper, temperature-dependent harmonic spectra of different commercially available single-core and multi-core particle systems were investigated for the determination of dominating relaxation mechanisms of magnetic nanoparticles.
