Special Issue Information

Dear Colleagues,

The current development of technologies requires a constant analysis of emerging materials. In this sense, the surfaces of implants and biomedical devices are constantly being improved by being subjected to physical, biochemical, and/or chemical treatments. The use of additive manufacturing has increased considerably in the last few years, as has the use of innovative devices.

This Special Issue is open to all medical specializations that can contribute information about advanced surface analyses for implants and biomedical devices, the characterization of ceramic devices, new metal alloys to be used as implant materials, innovations in microscopy software, the interpretation of soft tissue interactions with composites, bioceramics, polymers, and metal alloys.

The scope of this Special Issue will serve as a forum for research on the following concepts:

  • Surface treatments and tissue interactions.
  • Surface functionalization of biomedical devices.
  • Surfaces and materials for implants.
  • Recent insights into biomedical devices.
  • Surface characterization of dental materials.

In this Special Issue of Coatings, high-quality research from all biomedical fields that includes and improves the knowledge about surface analyses for implants and biomedical devices will be published.

Poly(dimethyl siloxane) (PDMS) is one of the most widely used materials in the biomedical field. Despite its numerous advantages, its hydrophobic character promotes bacterial adhesion and biofilm formation. For breast implants, biocompatibility is challenged due to the biofilm formed around the implant that can degenerate to severe capsular contracture over time. Thus, the laboratory has set up strategies to prevent bacterial contamination by grafting covalently hydrophilic bioactive polymers on the surface of implants. In this study, poly(methacrylic acid) (PMAc) and poly(acrylic acid) (PAAc) were chosen as non-toxic and biocompatible bioactive polymers known for reducing bacteria adhesion. These polymers are also good candidates to lend reactivity on the surface for further functionalization. X-ray photoelectron Spectroscopy (XPS) and Fourier-Transform Infrared spectroscopy (FTIR) analysis have highlighted the covalent grafting of these polymers. Apparent water contact angle measurements have shown the change in hydrophilicity on the surface, and a colorimetric assay allowed us to assess the grafting rate of PMAc and PAAc. Tensile strength assays were performed to ensure that the functionalization process does not significantly alter the material’s mechanical properties. Analyses of the surface aspect and roughness by Scanning Electron Microscope (SEM) and optical profilometer allow us to formulate hypotheses to approach the understanding of the behavior of the polymer once grafted.
