Special Issue Information

Dear Colleagues,

It is a great pleasure for me to introduce a Special Issue of Applied Sciences on the antiviral properties of carbon-based nanomaterials.

The aim of this Special Issue is to show the potential applications of carbon-based nanomaterials as novel anti-viral agents. The study of nanoparticles for the prevention of viral infections and of their capacity to suppress or decrease viral load is particularly timely, given the current pandemic.

Graphene (G) is one of the most studied carbon-derived nanomaterials because of its low cytotoxicity in biosystems and its chemical properties that allow binding of biomolecules and their subsequent intracellular delivery. The antibacterial properties of graphene derivatives are mostly due to the uptake of graphene nanoparticles and subsequent disruption of bacterial cells. Although an antiviral action of graphene-derived nanomaterials has been hypothesized by many authors, it has not yet been demonstrated.

We invite authors to submit innovative research papers or comprehensive review papers discussing how engineered nanoparticles exert anti-viral effects on biosystems. Papers that address both the delivery of anti-viral drugs to infected cells and the direct prevention of infections by nanoparticles are also welcome.

Dr. Stefania Mardente
Guest Editor

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. Applied Sciences 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 2400 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.

Background. New antiviral textiles for the protection and prevention of life-threatening viral diseases are needed. Graphene oxide derivatives are versatile substances that can be combined with fabrics by different green electrochemistry methods. Methods In this study, graphene oxide (GO) nanosheets were combined with textile samples to study GO antiviral potential. GO synthesized in the Chemistry laboratories at the University of Rome Tor Vergata (Italy) and characterized with TEM/EDX, XRD, TGA, Raman spectroscopy, and FTIR, was applied at three different concentrations to linen textiles with the hot-dip and dry method to obtain filters. The GO-treated textiles were tested to prevent infection of a human glioblastoma cell line (U373) with human herpesvirus 6A (HHV-6A). Green electrochemical exfoliation of graphite into the oxidized graphene nanosheets provides a final GO-based product suitable for a virus interaction, mainly depending on the double layer of nanosheets, their corresponding nanometric sizes, and Z-potential value. Results Since GO-treated filters were able to prevent infection of cells in a dose-dependent fashion, our results suggest that GO may exert antiviral properties that can be exploited for medical devices and general use fabrics.
