Special Issue Information
Dear Colleagues,
Nanofibers (NFs) have attracted widespread attention in fundamental research and technological applications because of their high aspect ratio, large specific surface area, and significant shape anisotropy. Doping NFs with magnetic nanoparticles resulting in magnetic nanofibers (MNFs) combines the advantages of both nanomaterials with synergistic effects.
The potential of MNFs in analytical chemistry can be exploited mainly in sample preparation, as sorbents in magnetic solid phase extraction, but also as pseudo-stationary phases in electrophoretic techniques and as contributors to enhance detection in electrochemical and optical (bio)sensors. Polymeric MNFs, after electrospinning, are the most popular option in chemical analysis, but magnetic cellulose NFs are of particular significance because the raw material, cellulose, is an economic and renewable source.
Analytical processes involving MNFs become faster, simpler, cheaper and greener, without selectivity or selectivity being hindered. However, when it comes to reproducibility, quality control of MNFs is a key aspect that enables comparison of results, either internally or externally, and these home-made materials are still a step behind the commercial ones in this way. Another important issue is to set up on-line, automated and/or miniaturized analytical platforms based on MNFs that enable the transfer to the productive sector.
The scope of this Special Issue is to gather contributions involving the use of MNFs in the analytical process, and the integration of the different steps, based of MNFs, into on-line, automated and/or miniaturized analytical systems. Applications in the environmental, food, and biological fields are encouraged. Other applications will be considered as well.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

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. Materials 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.
