Keynote Lecture: ZnP-ZnO dual-phase coatings on Zn foams with excellent antibacterial ability and biocompatibility for biodegradable orthopedic applications

Abstract: Zinc (Zn)-based biomaterials are receiving increasing attention as biodegradable metals due to their more suitable degradation rate than magnesium, iron, and their alloys. In this study, zinc phosphate (ZnP), zinc oxide (ZnO), and their dual-phase coatings were fabricated on a pure Zn foam via electrochemical anodization and subsequent phosphating. The dual-phase-coated foam sample showed a regular, almost spherical open-cellular interconnected porous structure with ~ 8 μm thick surface layer of ZnO and ZnP. Compressive test results showed that the dual-phase-coated foam sample exhibited a compressive yield strength of 1.8 and 1.1 MPa, a plateau strength of 2.9 and 2.7 MPa, and a compressive strain of 90% before and after 30 d immersion in Hanks’ solution. Biocompatibility assessment showed that the dual-phase-coated foam sample showed excellent cell viability toward MC3T3-E1 and MG 63 cells in both direct and indirect cell assays, and its 12.5% concentration extract showed ~ 107% cell viability of MC3T3-E1 cells and ~ 101% cell viability of MG 63 cells, indicating a positive effect on cell survival and proliferation. Moreover, the dual-phase-coated Zn foam sample exhibited effective antibacterial ability against S. aureus. Overall, the ZnO-ZnP dual-phase-coated Zn foam can be considered a promising biodegradable scaffold biomaterial for orthopedic applications.
