Novel Ferrites for Biomedical Applications

Dear Colleagues,

Ferrites, as magnetic materials, are attractive candidates for biomedical applications for diagnosis, therapeutics, control and treatment of diseases, enhanced MRI imaging, magnetic hyperthermia cancer treatment, targeted drug and gene delivery, biolabeling, biosensing, and antimicrobial agents, and enable the development of new medical devices.

Using ferrites as nanoprobes to label biomolecules offers the advantage of robust signal strength, sensitivity, and stability. Ferrite nanoparticles can be functionalized with different ligands to provide affinity for specific biological analytes to bind to the targeted surfaces, e.g., specific tumor types. Since the principle constituents of many ferrites, such as Fe, Mn, and Zn, exist as required metabolic minerals in the body, toxicity is rarely a limiting factor, unlike, for example, gadolinium-based MRI contrast agents.

Ferrite has the ability to alter physical properties in a tunable manner upon interacting with magnetic fields and specific analytes based on their intrinsic properties, morphology, spatial distribution, and conjugation. Such flexibility affords them unique potential as next-generation biomedical materials for such applications as drug delivery, imaging, sensing, diagnosis, and remediation of cancers.

The development of multifunctional ferrites to play more than one of these roles is the foundation of the burgeoning field of theranostics.

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. Magnetochemistry is an international peer-reviewed open access monthly 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 2200 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.
