Special Issue Information

Dear Colleagues,

In recent decades, research on the development and characterization of biomedical materials and thin films has received significant attention. There have been elaborated novel routes, which allow preparing biocompatible and bioactive materials and thin films with tailored properties for regenerative medicine, orthopaedy, and traumatology, cardiovascular applications, etc. The materials concern ceramics, metallics, and composites. In the case of biocompatible coatings, hybrid versions of different composition and structure have been reported, including biomimetic approaches. However, there are still a lot of challenges to address in order to establish the most promising fabrication approaches for a wide clinical application which meet the most important requirements.

Thus, this Special Issue is focused on the most recent results on the fabrication and characterization of the novel bioactive materials and thin films, which allow increasing the quality level of patients life suffering from injuries or loss of tissue.

This Special Issue will serve as a forum for papers on the following concepts:

  • Different methods for implant modification to improve surface bioactive performance;
  • Development and characterization of hybrid biomaterials and thin films using the biomimetic approach;
  • The results of in vitro and in vivo studies of implants with bioactive surface;
  • Topical reviews on the subject of recent progress in biomedical coatings;
  • The results revealing the structure–property relationship between material (implant) properties and biological or clinical applications;
  • Challenges facing the research community to provide widespread application of novel biomaterials and thin films.

In this work, an interdisciplinary approach was employed to investigate the impact on thermoplastic catheters from the deposition of a thin (180 nm), metallic silver film by a pulsed ablation technique. Our characterization firstly involved tensile and bending tests, each one accompanied by finite element modeling aiming to elucidate the contributions resulting from bulk and coating to the device’s mechanical behavior. The morphological assessment of the surface before and after the deposition was performed by atomic force microscopy, specifically implemented to visualize the nanostructured character of the film surface and the extent to which the polymer was modified by the deposition process, focusing on coating delamination due to tensile stress. Finally, thermogravimetric–differential thermal analysis was carried out to evaluate whether silver deposition has affected the physiochemical structure of the polymer matrix. Our results establish that the deposition does not significantly alter the physical and chemical properties of the device. The presented characterization sets a useful precedent for elucidating how structural properties of polymeric materials may change after coating by electronic ablation techniques, highlighting the importance of employing a comprehensive approach for clarifying the effects of additive manufacturing on medical devices.

Hydroxyapatite has become an important coating material for bioimplants, following the introduction of synthetic HAp in the 1950s. The HAp coatings require controlled surface roughness/porosity, adequate corrosion resistance and need to show favorable tribological behavior. The deposition rate must be sufficiently fast and the coating technique needs to be applied at different scales on substrates having a diverse structure, composition, size, and shape. A detailed overview of dry and wet coating methods is given. The benefits of electrodeposition include controlled thickness and morphology, ability to coat a wide range of component size/shape and ease of industrial processing. Pulsed current and potential techniques have provided denser and more uniform coatings on different metallic materials/implants. The mechanism of HAp electrodeposition is considered and the effect of operational variables on deposit properties is highlighted. The most recent progress in the field is critically reviewed. Developments in mineral substituted and included particle, composite HAp coatings, including those reinforced by metallic, ceramic and polymeric particles; carbon nanotubes, modified graphenes, chitosan, and heparin, are considered in detail. Technical challenges which deserve further research are identified and a forward look in the field of the electrodeposited HAp coatings is taken. Full article
