Special Issue Information

Dear Colleagues,

At present, the academic and industrial research efforts to improve the lifespan of bone implant materials are growing more and more due to an increasing worldwide clinical demand in skeletal repair, particularly for orthopaedic and dental surgeries. To reach this objective, many research labs focus their works on improving the osseointegration of bone implants by modifying the surface of prosthetic alloys with bioactive coatings made of bioceramic or bioglass. These coatings support the bone cells’ growth at the surface of the implant, promoting the formation of an intimate link with the surrounding bone tissues.

The electrochemical methods, such as electrochemical deposition and electrophoretic deposition, are powerful low-temperature processes to design innovative bioactive coatings to produce new biomaterials. The deposition parameters and the experimental conditions control the thickness and the chemical composition of these coatings. Moreover, since electrochemical deposition and electrophoretic deposition take place at low temperature, the incorporation of organic components (polymers, proteins, drugs, etc.) inside the prosthetic coating is possible in order to enhance the biological and mechanical properties of the surface coating.

In that framework, this Special Issue aims at presenting the latest developments in this field.

In particular, the topics of interest include but are not limited to:

  • Recent developments in electrochemical deposition;
  • Recent developments in electrophoretic deposition;
  • Synthesis of functionalized prosthetic coatings;
  • Calcium phosphate coatings for bone implants;
  • Bioglass coatings for bone implants.

Curcumin-Containing Orthopedic Implant Coatings Deposited on Poly-Ether-Ether-Ketone/Bioactive Glass/Hexagonal Boron Nitride Layers by Electrophoretic Deposition

Abstract
Electrophoretic deposition (EPD) was used to produce a multilayer coatings system based on chitosan/curcumin coatings on poly-ether-ether-ketone (PEEK)/bioactive glass (BG)/hexagonal boron nitride (h-BN) layers (previously deposited by EPD on 316L stainless steel) to yield bioactive and antibacterial coatings intended for orthopedic implants. Initially, [...] Read more.
Electrophoretic deposition (EPD) was used to produce a multilayer coatings system based on chitosan/curcumin coatings on poly-ether-ether-ketone (PEEK)/bioactive glass (BG)/hexagonal boron nitride (h-BN) layers (previously deposited by EPD on 316L stainless steel) to yield bioactive and antibacterial coatings intended for orthopedic implants. Initially, PEEK/BG/h-BN coatings developed on 316L stainless steel (SS) substrates were analyzed for wear studies. Then, the EPD of chitosan/curcumin was optimized on 316L SS for suspension stability, thickness, and homogeneity of the coatings. Subsequently, the optimized EPD parameters were applied to produce chitosan/curcumin coatings on the PEEK/BG/h-BN layers. The multilayered coatings produced by EPD were characterized in terms of composition, microstructure, drug release kinetics, antibacterial activity, and in vitro bioactivity. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) confirmed the deposition of chitosan/curcumin on the multilayer coating system. The release of curcumin upon immersion of multilayer coatings in phosphate-buffered saline (PBS) was confirmed by ultraviolet/visible (UV/VIS) spectroscopic analysis. The antibacterial effect of chitosan/curcumin as the top coating was determined by turbidity tests (optical density measurements). Moreover, the multilayer coating system formed an apatite-like layer upon immersion in simulated body fluid (SBF), which is similar in composition to the hydroxyapatite component of bone, confirming the possibility of achieving close bonding between bone and the coating surface.
