Special Issue Information

Dear Colleagues,

It is our great pleasure to announce this Special Issue, “Advanced Coatings and Materials for Biomedical Applications”, which will be published in Coatings.

The evolution of advanced materials and coatings has fundamentally transformed the domain of biomedical applications, providing groundbreaking solutions to improve the performance, biocompatibility, and durability of medical devices and implants. As biomedical technologies continue to evolve, there is a growing demand for materials and coatings that can impart multifunctional properties.

These innovative materials have unique properties, including enhanced strength and flexibility, improved corrosion resistance, targeted drug delivery capabilities, antimicrobial activity, and enhanced biological integration. They are used in a variety of applications, including medical implants, prosthetics, drug delivery systems, and regenerative tissue scaffolds. These materials significantly improve patient outcomes and advance personalized medicine.

This Special Issue aims to highlight recent advancements and innovative fabrication techniques that enable biomedical materials and coatings to meet the complex demands of modern medicine. The objective is to promote a better understanding of the materials and methods that will influence the future of biomaterials and enhance patient care worldwide.

Calcium phosphates are one of the main materials used in biomedicine for bone regeneration purposes. To improve the properties of biocompatible β-Ca3(PO4)2, doping by bioactive, antibacterial is actively used, as well as luminescent ions. Co-doped phosphates Ca8−xSrxZnEu(PO4)7 with a β-Ca3(PO4)2 (β-TCP)-type structure were synthesized through solid-state synthesis. The β-TCP-type structure was confirmed using X-ray powder diffraction and FTIR spectroscopy. Photoluminescence data, including excitation and emission spectra, decay curves, lifetime values and quantum yields, were collected for all samples. Ca8−xSrxZnEu(PO4)7 phosphates exhibit strong red-emission due to 4f-4f transitions of Eu3+ ions in disordered oxygen surrounding, with quantum yields reaching 54%. The phosphates demonstrated biocompatibility through MTT assay, with successful differentiation of aMSCs into the osteogenic lineage. Antibacterial activity was tested against four bacteria (E. coli, S. aureus, P. aeruginosa, and E. faecalis) and a fungus (C. albicans). It was found that the samples demonstrated antibacterial properties. The growth of E. coli and E. faecalis is significant inhibited by Ca8−xSrxZnEu(PO4)7 samples with 0 ≤ x ≤ 6.0. Analysis of mixed salt solubility using Eu3+ ions as a fluorescent probe showed that increasing Sr2+ concentration in Ca8−xSrxZnEu(PO4)7 delays both β-TCP phase resorption and HAP phase precipitation. These results demonstrate the potential of Ca8−xSrxZnEu(PO4)7 phosphates for bioimaging and bone healing control. Full article
