Special Issue Information

Dear Colleagues,

Diamond-like carbon coatings (DLCs) deposited using many different CVD or PVD techniques still arouse invariable interest in the field of biomedical applications. Today, there is the possibility of doping amorphous layers with different elements or compounds, like carbides, oxides, or nanostructures. The application of DLCs in multilayer structures, their plasma, and chemical surface modification are used for designing the properties of biomaterials. We can manufacture diamond-like carbon coatings with different chemical compositions, structures, and topographies in order to obtain an appropriate biological response. The discovery of new solutions in biomedical applications and the improvement of modern implants is possible through the surface modification of DLC coatings. The purpose of this Special Issue is to show current trends taking advantage of the surface modification of DLC coatings. Articles showing the relationships between the technological parameters and biological characteristics, including the possibilities of doping DLC coatings, their plasma, or chemical surface modification, as well as the application of DLC in multilayer structures, will be appreciated. In addition, thanks to these contributions, it will be possible to show the development trends of the current research in this field.

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.

Silver and copper as additives of various biomaterials have been reported as the potential solutions for biomedicine applications, mostly because of inducing bactericidal effects. The application of those admixtures in diamond-like carbon (DLC) coatings may be desirable for orthopedic implants. In the present manuscript, the biological effect of coatings with up to about 7 at.% and 14 at.% of, respectively, Cu and Ag is compared. The morphology, chemical structure, and composition of films deposited on AISI 316LVM and Ti6Al7Nb is characterized. The live/dead analysis conducted with Escherichia coli shows a higher bactericidal potential of silver than copper. Although the Cu-doped coatings can positively affect the proliferation of Saos-2 and EA.hy926 cell lines, the results of XTT test are on the verge of 70% of viability. Biological effect of silver on EA.hy926 cell lines is negative but that admixture ensures high proliferation of osteoblasts in contact with coatings deposited on titanium alloy (over 20% better than for substrate material). In that case, the viability is reaching about 85% for Ag-doped coatings on AISI 316LVM and 75% on Ti6Al7Nb. The results indicate that for the sake of bactericidal coatings that may promote osteointegration, the candidates are DLC with silver content no higher than 10 at.%. Full article
