Special Issue Information

Dear Colleagues,

This Special Issue of Materials focuses on novel technologies and applications in the range of electrospun nanofibers and nanofiber mats. Electrospinning enables the creation of fibers in the sub-micrometer range, i.e., with a high surface-to-volume ratio, allowing us to apply them in biotechnology, for medical and filter applications, among others. On the other hand, such nanofibers are known to have low defect rates, making them useful in material investigations. Recently, new needleless electrospinning technologies are being established, aiming at higher productivity, thus bringing these materials nearer to commercial applications on larger scales. On the other hand, new materials and material blends are being investigated to further broaden the spectrum of possible applications. Finally, the area of "green electrospinning" is gaining more and more interest, reducing and preferably avoiding hazardous solvents. We would like to invite you to contribute to this Special Issue on “Electrospinning: Nanofabrication and Application”. Here, we will underline recent advances in relation to technology, materials science, and basic research for diverse applications. Research topics of interest may include, but are not limited to, new needleless electrospinning techniques, new applications of electrospun nanofiber mats, new materials and material blends used for electrospinning, tailoring physical and chemical properties of electrospun nanofiber mats, as well as generally new ideas centered around electrospinning.

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.

Pomegranate peel extract is known for its potent antibacterial, antiviral, antioxidant, anti-inflammatory, wound healing, and probiotic properties, leading to its use in treating oral infections. In the first stage of this work, for the first time, using the Design of Experiment (DoE) approach, pomegranate peel extract (70% methanol, temperature 70 °C, and three cycles per 90 min) was optimized and obtained, which showed optimal antioxidant and anti-inflammatory properties. The optimized extract showed antibacterial activity against oral pathogenic bacteria. The second part of this study focused on optimizing an electrospinning process for a combination of polycaprolactone (PCL) and polyvinylpyrrolidone (PVP) nanofibers loaded with the optimized pomegranate peel extract. The characterization of the nanofibers was confirmed by using SEM pictures, XRPD diffractograms, and IR-ATR spectra. The composition of the nanofibers can control the release; in the case of PVP–based nanofibers, immediate release was achieved within 30 min, while in the case of PCL/PVP, controlled release was completed within 24 h. Analysis of the effect of different scaffold compositions of the obtained electrofibers showed that those based on PCL/PVP had better wound healing potential. The proposed strategy to produce electrospun nanofibers with pomegranate peel extract is the first and innovative approach to better use the synergy of biological action of active compounds present in extracts in a patient-friendly pharmaceutical form, beneficial for treating oral infections.
