Special Issue Information
We warmly invite you to submit your recent work in the field of synthesis and characterization techniques of hydroxyapatite (HA) coatings to the Special Issue “Synthetic and Biological-derived Hydroxyapatite Implant Coatings”.
In the last few decades, the field of bioactive materials for bone tissue engineering has emerged as one of the prominent approaches to tackling bone traumas and ailments, with an emphasis on the production of durable implants and bone substitutes capable of bypassing rejection complications.
HA is a well-known bioceramic which possesses a close chemical and structural resemblance to the mineral composition of bones and teeth of vertebrates. Despite their favorable bone regeneration properties, HA ceramics are very brittle, and this restricts their usage in high load-bearing applications. To overcome this drawback, HA can be applied as a coating on either metallic or polymeric implants, aiming to significantly improve the implant’s overall performance by harmoniously combining the excellent bioactivity of the ceramic with the mechanical advantages of the substrate implants.
Synthetic HA is commonly produced by several chemical routes, but recent methods to either extract or derive HA from natural sustainable resources (e.g., bones, sea-shells, various mineralogical resources) were reported. Biological-derived apatite is a carbonated HA, which contains various amounts of oligoelements and has a reduced crystallinity. Therefore, it differs from synthetic HA in terms of composition, stoichiometry, crystallinity degree, crystal size/morphology, and thus, degradation rate and overall biological performance.
Moreover, commercial thick plasma-sprayed HA coatings are susceptible to cracking and delamination and, owing to the high processing temperatures, could contain residual decomposition phases. In this respect, current research interests are rapidly advancing on two focused directions: (i) Increasing the biomimicry of HA coatings with respect to the composition and structure of bone apatite, and (ii) improving the present or even discovering alternative deposition techniques to allow for the fabrication of novel (doped) HA coatings with increased mechanical and biological performance.
In particular, the topics of interest of this Special Issue include, but are not limited to:
- Synthetic and biological-derived HA coatings for orthopedic and dental implants;
- Drug delivery;
- Composite HA-based coatings;
- Doping of synthetic and biological-derived HA coatings;
- Alternative methods for the deposition of synthetic and biological-derived HA coatings;
- Biofunctional assessment of synthetic and biological-derived HA coatings.
