Synthesis, Properties and Applications of Magnetite Nanoparticles

Dear Colleagues,

In recent years, magnetite nanoparticles have been increasingly used in a number of applications in nanotechnology and biomedicine. Due to its nontoxicity and long circulation in the bloodstream, magnetite is a material of choice for these applications. Magnetite nanoparticles can be functionalized with various molecules and used for various techniques. Such applications include their use in gene and drug delivery, their use in targeted hyperthermia, and their use as MRI contrast agents. To better implement these applications, it is important to well understand the structural and magnetic properties of assemblies of such nanoparticles, both at the macroscopic and nanoscopic scales, in various environments of magnetic field and of temperature, and the possible dependence of these properties on particle size and shape. In this Special Issue, we will review recent progress in the fabrication of magnetic nanoparticles of various sizes and shapes, as well as in the characterization of their properties, using state-of-the-art tools such as magnetometry, magnetic imaging, Mossbauer spectroscopy, neutron scattering, X-ray magnetic scattering, and photon correlation spectroscopy. In addition to the experimental work, this Special Issue will also include theoretical and modeling work, useful to better understand the spatial and temporal nanoscale behavior of magnetite nanoparticles. Lastly, this Special Issue will present a survey of applications of magnetite nanoparticles in a diversity of nanotechnology applications.

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. Nanomaterials 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 2900 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.
