Special Issue Information
Dear Colleagues,
Frequency mixing magnetic detection (FMMD) has been well-established for more than 15 years as a sensitive and very selective technique to quantitatively probe magnetic nanoparticles by their nonlinear responses to a two-frequency magnetic excitation field. The method has been applied for numerous magnetic immunoassays of different biological targets, such as viruses, proteins, bacteria, toxins and cells, with better sensitivities and detection ranges than the standard enzyme-linked immuno sorbent assay (ELISA) techniques. In this Special Issue; the fundamentals of FMMD methodology will be comprehensively explained, the design and realization of FMMD instrumentation will be presented; and various FMMD applications from the fields of biomedicine, nanomaterials characterization and even the non-destructive evaluation of fatigue will be highlighted. In particular it will present how offset field scanning is employed to determine the core size distribution of magnetic particles; a phase evaluation allows for the assessment of the Brownian relaxation, yielding information on the binding state of magnetic particles to biological targets; FMMD has been applied as a detection modality for magnetic particle imaging (MPI).

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
