Special Issue Information

Dear Colleagues,

It is my great pleasure to introduce you to this new Special Issue of Applied Sciences, “State of the Art of Antibacterial Materials and Coatings”. Scientific interest on the development and characterization of antibacterial materials has been exponentially growing since the late 1970s, to the point that most existing materials, either synthesized or naturally available, have been tested at least once for their antibacterial properties.

It is now time to consolidate the scientific evidence into a state-of-the-art review, which we hope will represent a starting point for future research in this field. Papers concerning new testing methods, characterization of innovative materials, multi-strain studies, comparisons and potential antibacterial applications of conventional materials are welcome for submission.

Potential topics include, but are not limited to, the following:

  • Antibacterial coatings for biomedical applications;
  • Food packaging materials;
  • Bio-based antibacterial composites;
  • Antibacterial filters and membranes;
  • Biodegradable antibacterial materials;
  • Antifungal materials and coatings;
  • Bacteria fouling and fouling prevention.

Prof. Dr. Elia Marin
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.

The performance, durability, and bio-integration of functional biomedical coatings can be enhanced by changing or improving their substrate properties. In this study, we applied silicon nitride powder-based laser claddings to various substrates and undertook an in vitro assessment of their osteoconductive and antibacterial properties. The substrates included common arthroplasty materials: polyethylene, titanium, zirconia-toughened alumina, and zirconia. Multiple analytical techniques were used to characterize the physical and chemical structure of the claddings after deposition. Partial decomposition of the silicon nitride powders occurred during the cladding process, resulting in nitrogen loss during intermetallic formation phases under some substrate and treatment conditions. The osteoconductive capabilities of various laser-cladded substrates were evaluated in a SaOS-2 osteosarcoma cell culture by measuring the amount of bone formation on the coated surface. Antibacterial testing was performed using Gram-positive Staphylococcus epidermidis at 24 and 48 h of incubation. Silicon nitride coating enhanced both osteoconductive and antibacterial properties.
