Special Issue Information
Dear Colleagues,
Bioactive coatings have emerged as a pivotal technology in materials engineering, medicine, and tissue engineering because of their unique surface functionalization and the ease with which we can modulate their biocompatibility. By precisely tailoring the composition and structure of these coatings, we can give materials antibacterial properties, promote cell adhesion, enable controlled drug release, or facilitate tissue regeneration, offering innovative solutions for medical devices, implants, and biomaterial development. This Special Issue focuses on cutting-edge research in this field, aiming to foster interdisciplinary collaboration from the fundamental characterization to clinical translation of bioactive coatings.
This Special Issue will focus on bioactive coatings that modulate biological responses through tailored surface chemistry, nanostructures, or stimuli-responsive properties. Contributions are invited on topics including, but not limited to, the following:
1. Coating Design and Fabrication
- Surface Functionalization: The development of biocompatible coatings via chemical modification (e.g., hydroxyapatite, collagen, polylactic acid) and nanostructuring.
- Multifunctional Materials: The synthesis of nanocomposites that contain antibacterial agents, growth factors, or conductive components.
- Biomimetic Strategies: Coatings inspired by natural systems (e.g., extracellular matrix mimics, self-healing mechanisms).
2. Advanced Characterizations and Mechanisms
- Structure–Bioactivity Correlation: Microstructural analysis of the structure (porosity, roughness) of bioactive coatings and its impact on cell adhesion, proliferation, and differentiation.
- In Vitro/In Vivo Evaluation: Mechanical stability, degradation kinetics, and biosafety assessments using techniques like XPS, SEM, and in vivo models.
- Surface–Cell Interactions: The mechanisms behind functional group grafting, protein adsorption, and the signaling pathways triggered by coatings.
3. Biomedical Applications
- Medical Devices: Antimicrobial coatings for catheters, orthopedic implants, and surgical tools to prevent infections.
- Implant Surface Modification: Osteoinductive coatings (e.g., bioactive ceramics on titanium alloys) for enhanced integration.
- Drug Delivery Systems: Smart coatings that enable the spatiotemporal release of antibiotics, growth factors, or anticancer agents.
- Tissue Engineering: Functional coatings guiding vascularization, cell alignment, and extracellular matrix formation in scaffolds.
4. Emerging Technologies and Challenges
- 3D-Printed Coatings: Complex architectures for tailored mechanical and biological properties.
- Stimuli-Responsive Systems: Coatings activated by pH, temperature, or enzymes for precision medicine.
- Clinical Translation: Preclinical validation of long-term stability, standardized evaluation protocols, and regulatory compliance.
5. Cross-Disciplinary Frontiers
- AI-Driven Design: Machine learning for optimizing coating composition and performance.
- Sustainability: Eco-friendly coatings and biodegradable materials for greener applications.
- Commercialization Pathways: Strategies for scaling up production and bridging academic research with industry needs.
