Special Issue Information

Dear Colleagues,

We are thrilled to announce the release of Volume II of our Special Issue, "Advances in Surface Engineering and Biocompatible Coatings for Biomedical Applications". The previous volume contained 14 published articles and garnered substantial interest, with 24056 views at the time of writing and 40 citations in less than a year. We are certain that the release of Volume II will advance the field by gathering critical reviews and cutting-edge research articles, with similar interest and success. Below is a summary of the goals, objectives, and scope of this Special Issue.

The surface characteristics of biomaterials, including roughness, wettability, antibacterial activity, chemical composition, electrical charge, crystallinity, modulus, and hardness, have a significant impact on their performance as they influence various factors, from biocompatibility to protein adsorption, anti-inflammatory properties, adhesion, and tribological and corrosion behaviours. The surface modification of bulk materials, such as metal alloys, polymers, and ceramics, is essential for addressing significant performance issues, such as a lack of osseointegration, infections, toxicity, low corrosion/wear resistance, and inadequate antibacterial activity. Modifying the surface properties of bulk materials and applying biocompatible coatings lead to significant improvements in biomaterials’ performance and longevity by altering their surface properties, showing potential for facilitating the formulation of effective strategies to tackle specific clinical requirements.

This Special Issue seeks to emphasize the recent progress in surface engineering and biocompatible coatings for biomedical applications. Our objective is to publish a minimum of ten articles of exceptional quality, at which point this Issue could be published in book format. We encourage the submission of original research articles and critical reviews on the following possible research areas (but not restricted to them):

  • Mechanical and physical surface treatment, including grit blasting, polishing, shot peening, water jet shot peening, surface mechanical attrition treatment, laser peening, sputtering, laser/electron beam patterning, and plasma electrolyte oxidation;
  • Chemical and electrochemical surface treatment, including etching, anodizing, sol–gel, nitriding, electrophoretic deposition, PVD, and CVD;
  • Biocompatible coatings, including hydroxyapatite-, bioactive glass-, and polymer-based coatings;
  • Understanding the tribological and corrosion behaviours of biomaterials.

We thank you for your interest and look forward to receiving your contributions.

Abstract
Spinal cord injury (SCI) treatment remains challenging globally, with limited breakthroughs. Tissue engineering offers promise, particularly using acellular spinal cord scaffolds. This study developed a 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC)-crosslinked vascular endothelial growth factor (VEGF)-modified acellular spinal cord scaffold for sustained VEGF release.

Spinal cord injury (SCI) treatment remains challenging globally, with limited breakthroughs. Tissue engineering offers promise, particularly using acellular spinal cord scaffolds. This study developed a 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC)-crosslinked vascular endothelial growth factor (VEGF)-modified acellular spinal cord scaffold for sustained VEGF release. The results show sustained VEGF release over 20 days without altering the scaffold’s properties. Enhanced stability and mechanical properties were observed without increased cytotoxicity. In a rat SCI model, the system improved motor function, reduced glial scarring, and restored spinal cord morphology and histology, indicating potential for SCI therapy. Full article

Teeth have excellent mechanical properties, with high wear resistance and excellent fracture resistance. This is due to their well-organized multilevel hierarchical structure. While a number of studies in the last decades have revealed the relationship between tooth structure and mechanical properties, there is still no general agreement on how different orientations of hydroxyapatite (HAp) fibers affect the mechanical properties of enamel. With a scanning electron microscope and nanoindenter, the orientations of HAp fibers and their properties were investigated. HAp fibers have two different orientations: parallel and perpendicular to the surface. Fibers oriented parallel to the surface exhibited higher hardness, elastic modulus and wear resistance. Under applied force, fibers oriented perpendicular to the surface suffered deeper shearing in the protein along the long axis, resulting in lower mechanical properties. Teeth resist damaging fractures by combining hard and soft structures. This study may lead to new insights into how nature selects for tooth structure and provide a theoretical basis for the bioinspired design. Full article
